Hi there - thanks for taking out the edits on Iodine value I had made on my tablet - I guess I thought I would get back quicker to do the things I had tried to suggest. Could you have a look and see what you think of the next version - there were some things in my edit which I can only see as being worth keeping such as the spelling of organoi(o)dine compounds - I could not see what the weak chemistry was you mentioned in the reversion comment.

Acetylene edits

Thank you for looking over my work once again. I will take your critiques to heart and make some appropriate changes. I agree about my illustration, it is a butt-ugly eyesore. I just thought I would draw it because the whole article set a precedence for pictures (i.e. I didn't want my submission be the only one to break the format). Anyways... I first learned of this from Ullmann's too but the coverage was a mere paragraph. The Walter Reppe 1969 source source says iron pentacarbonyl can be used as reagent when no free carbon monoxide is available to recharge the catalyst. The equation yielding iron(II) carbonate is taken verbatim from the 1969 paper. For chemists without a lab fitted with special hazard insurance (i.e. being OK'd to work with carbon monoxide), I thought small-time experimenters ought to know they can work with a relatively safe solid reagent rather than a highly poisonous gas.

As a side note on the topic of the iron pentacarbonyl usage, the 1969 source says the reaction between methylacetylene and dimethylacetylene is highly selective (regardless of stichometry) favoring 1,2,4-trimethylhydroquinone, a precursor for the total synthesis of Vitamin E. It also says that higher alkyl groups work as well for this method. Looks to me that this sort of reaction could have industrial applications (considering aromatic substitution is a pain in the ass). The author also explains the reason for this type of synthesis "going out of style" is because petroleum's rise to dominance over the prior calcium carbide industry (and acetylene's cheaper petroleum replacement ethylene). We all know that is a problem considering that we, as a species, are rapidly depleting our oil reserves. Definitely an opportunity to invent new, cheap, "future proof" syntheses of substituted aromatics...

As for topic reccomendations, besides the other occasional curiosities, I am interested in sourcing chemical reagents from renewable resources (i.e. practical yet unconventional total syntheses of reagents). It's fun to think (mostly waste time) over. If you have something weird for me in a secondary source please shoot away, I will give it a look. --ThunderSkunk (talk) 21:23, 7 January 2014 (UTC)

Well, I learned something about the hydroquinone synthesis, thanks. I thought that you blew it with ferrous carbonate and had intended to write Fe(CO)₃. There is a huge amount of stuff in the Reppe area, but the main apps are hydrocarbonylation and hydroesterification of alkenes and alkynes.

The main challenge is notability, that is the reason that Wiki policy places so much emphasis of WP:SECONDARY (books and reviews). In this spirit I recommend a new review on acetylene chemistry doi:10.1021/cr400357r. Even if you do not have a subscription, you can view the articles outline.

Re your comment about the depletion of our petrochemical reserves. My understanding also is that cheap petroleum destroyed the coal-based chemical industry. Thank god though! Calcium carbide based chemistry is filthy and is probably only practiced in PRC and other places that tolerate pollution associated with making that crud. Petrochemicals are here for a long time, esp in view of cheap natural gas. Cheers,--Smokefoot (talk) 01:37, 8 January 2014 (UTC)

Boron nitrate

This looks rather odd. The "references" seem to be to boron nitride, the usual spelling mistake. The unreferenced preparation is tribromide plus nitric acid. All seems like a mistake to me. If you agree can we get it deleted?Axiosaurus (talk) 13:30, 27 January 2014 (UTC)

Well that is an odd one. As we know, all sorts of articles get entered and the dubious ones have weak refs. I guess someone must have made the nitrate ester of boric acid, but I had not heard of it. Will look around as the opportunity arises. --Smokefoot (talk) 16:02, 27 January 2014 (UTC)

Here is a reference that says it does not exist: http://www.geothermal-energy.org/pdf/IGAstandard/WGC/2005/0207.pdf but of course there could be a later one that says it does.

"Cut-and-paste move"

Hi, and thank you for your contributions to Misplaced Pages. It appears that you tried to give Diimine a different title by copying its content and pasting either the same content, or an edited version of it, into another page with a different name. This is known as a "cut-and-paste move", and it is undesirable because it splits the page history, which is legally required for attribution. Instead, the software used by Misplaced Pages has a feature that allows pages to be moved to a new title together with their edit history.

In most cases, once your account is four days old and has ten edits, you should be able to move an article yourself using the "Move" tab at the top of the page. This both preserves the page history intact and automatically creates a redirect from the old title to the new. If you cannot perform a particular page move yourself this way (e.g. because a page already exists at the target title), please follow the instructions at requested moves to have it moved by someone else. Also, if there are any other pages that you moved by copying and pasting, even if it was a long time ago, please list them at Misplaced Pages:Cut-and-paste-move repair holding pen. Thank you. Christian75 (talk) 16:30, 31 January 2014 (UTC)

Thanks for the reminder. Although I might err in some cases, I usually follow official protocol. It would be nice to have the authority to switch the target title to an existing redirect without needing to ask for an administrator, but I get lots of help. It looks like the move that I wanted was implemented by fellow editor Edgar181. I need to go back and tidy up the redirects. Cheers, --Smokefoot (talk) 20:18, 31 January 2014 (UTC)

Fluoride

I saw your edit for Fluoride: https://en.wikipedia.org/search/?title=Fluoride&oldid=596071903 I could see why you removed my newer sections as I mistooke that I was posting on the ion form of fluorine. I wanted to ask a few questions though: you removed the secion: "===Inorganic chemicals=== Fluorides are pervasive in modern technology. Hydrofluoric acid is the fluoride synthesized on the largest scale. It is produced by treating fluoride minerals with sulfuric acid. Hydrofluoric acid and its anhydrous form hydrogen fluoride are used in the production of fluorocarbons and aluminium fluorides. Hydrofluoric acid has a variety of specialized applications, including its ability to dissolve glass. See this book: Aigueperse, Jean (2005). "Fluorine Compounds, Inorganic". Ullmann's Encyclopedia of Industrial Chemistry. Weinheim: Wiley-VCH. p. 307. doi:10.1002/14356007.a11_307. ISBN 978-3527306732. {{cite encyclopedia}}: Unknown parameter |coauthors= ignored (|author= suggested) (help)

Mined fluorite (calcium fluoride) is a commodity chemical used in steel-making. Cryolite, Na₃AlF₆, is the next highest fluoride salt in industry. It is used in aluminium smelting. Formerly, it was mined, but now it is derived from hydrogen fluoride. Various other fluoride salts are used as fluxes or for the preparation of other fluorine compounds, including covalently bonded fluorochemicals." I didn't create this section but it seems to stay on subject for fluoride, I thought it should stay and I'm new to editing on wiki but I remember reading I should ask the editor if possible before reverting parts of their edits.

Also, for one of the citations you removed info, from: "<ref>{{vcite article |url=http://www.who.int/water_sanitation_health/dwq/chemicals/en/fluoride.pdf |format=PDF |year=2004 |title=Fluoride in drinking-water |author=World Health Organization}}</ref>" to: "<ref>http://www.who.int/water_sanitation_health/dwq/chemicals/en/fluoride.pdf</ref>" I've been including title and such from my citations, are you not supposed to? I want to make sure I'm not missing something. Thank you for your help.

Thanks for the note. I hope that you will have a positive experience. The nature of your impact will improve by (i) communicating with established editors and (ii) making small changes initially.

In any case, the fluoride article is on F and related salts. At least that is the direction that the article has taken. I did not check to see if the chloride, bromide, halide etc articles are similar. You quickly can realize that there is a lot of opportunity for disciplined writing/content.

One issue that I often contend with is that infrequent editors fail to appreciate the huge prosaic applications. Instead, we get a lot of editors who want to mention their hobby (e.g. aquariums, stain removal, grandma's ant poison) or their college essay/publication as being something really important, when in fact they are negligible and obscure the big picture. Hence the need to focus fluoride on its role in aluminium and steelmaking, which really dominate. On the other hand, the use of fluoride in dental care is highly impactful, but consumes tiny fraction of the world's fluoride supply.

About the link "<ref>http://www.who.int/water_sanitation_health/dwq/chemicals/en/fluoride.pdf</ref>" You are welcome to revise if you think that I messed up. My recollection is that the link was non-functional (they call this link-rot around here) so I tweaked it.

And the RSC links and WebElements links that I am disinclined toward. These websites do not seem (to me) to be particularly authoritative. They probably/possibly borrow content from Misplaced Pages or chemical catalogues. I view them as quasi-adverts for some organization, such as the RSC.

I hope that this extended answer is helpful. Feel free to ask more or just go edit. Cheers, --Smokefoot (talk) 18:05, 19 February 2014 (UTC)

Thank you for the feed back, and clarification. I'll double check the link for what I was thinking but it makes more sense now. As for RSC it seem informative. I've listen to many of their podcasts and for the elements podcasts they are each produced by different professions. They mention a lot of the same information but that leads me into the other point you mentioned, about the Inorganic section. As a reader and someone that has mainly used Misplaced Pages for school, it seems relavant to me to include as much of the uses for a compound or an element as with fluoride isn't steelmaking or aluminium or for dental care in the big picture. The reason I even started looking it up was to look at alternative uses, but it was a little confusing the overlap between fluoride and fluorine that and the names being similar didn't help, and I made a silly mistake on my part. The inorganic section seems very relavant as I was most intrested in the inorganic properties, which does get into steel making and such, but there are so many other research sections. How do you think it would work best to include the rich diversity of an element such as F, but not include filler? I ask, only because I don't have a good answer myself. That said, maybe put the steel and aluminum section under inorganic chemistry and just have the uses divided by class of chemistry?

Butoxyethanol

Hi Smokefoot! Thanks for all your help and edits with the 2-butoxyethanol page. We will try to make our sources more international and we will look into other sources. Blairwal (talk) 20:05, 19 February 2014 (UTC)

Perchlorate Suggestion

Hi, thank you so much for your help and suggestions. However, I came across some questions.
1) Be sure to emphasize secondary sources, i.e. reviews and books. See WP:SECONDARY. Absolutely required for biomedical citations per WP:MEDRS. -- How do I emphasize secondary source on bibliography?

You should mainly cite secondary sources. Articles that say they are reviews. Naive editors often like to cite fairly narrow journal articles but you dont know enough to do that well (no offense). Professors and a handful of experts are really able to cite primary literature well.

2) If you find you are using the word "recently", don't. We are not interested in news per WP:NOTNEWS. -- I haven't used recently but all I said was "it is currently a subject of legal action". Should I not use currently either?

If something is "currently… anything" then leave it out. Misplaced Pages is not a blog. Your content is frozen in time largely. So then two years from now someone reads your content and sees that "it is currently a subject of legal action" which is obsolete because currently was very yesterday.

3) The article is international, so do not assume exclusively US perspective. Far more readers live outside of US than inside. An essay on US regulations is inappropriate. -- I just gave what US is doing as an example. Should I just remove a discussion on US government?

then make sure that you indicate a US perspective. The EPA and FDA are the U.S. EPA and the U.S. FDA. It is a tiring to read the content from US students who are oblivious of the fact that they are a minority of readers.

4) The article is about a chemical species, not its environmental impact per se. So be balanced per WP:UNDUE. -- For part of the project, we are researching on how these chemicals are affecting humans and environment. The article already seems to have health issues involved. Would including more health issues and environment be a problem?

Just be mindful that there is a ton of (often mediocre or redundant) literature on tox and environmental stuff. So be careful. Remind your instructor that length does not correlate with excellence. We do not want the MSDS reiterated. See Misplaced Pages:Manual of Style/Chemistry#Safety.

Out of line

You are out of line. The paper in question is published on the World Health Organization site, and is CLEARLY a secondary source, if you had bothered to examine it, as evidenced by the numerous other primary and secondary sources at the bottom of the page. I would encourage you to read the information you posted regardless, as nowhere does it bar even primary sources, stating that they should be backed up by secondary sources whenever possible if making "an interpretation", which I was certainly not doing! It is common and accepted practice to cite the same article more than once on a Wiki page. And FTR, I am not at all affiliated with any of the publishers,researchers, or authors in question! The information you wantonly deleted was cited in multiple sources, is factually accurate, and widely accepted. You seem to have a minor fixation on the issues of "sourcing" and COI. I encourage you to rethink your actions in the future to avoid conflict with your fellow editors.Jbtvt (talk) 14:38, 27 February 2014 (UTC)

Well I dont completely agree, adding many references to a single research group is highly unusual. Judging from the number of publications on lead poisoning or chelation, one can appreciate the difficulty in selecting references. Self-citation is a problem in Misplaced Pages that conveys distorted information, hence my concerns. In any case, thanks for being careful and I hope that I am indeed in the wrong. --Smokefoot (talk) 18:18, 27 February 2014 (UTC)

Hi, I saw your message on my Talk page and just wanted to thank you for the help you've provided for my work on 2-Butoxyethanol. My contribution to the article is for a class on environmental disruptors and I'm pretty new to Misplaced Pages. What I was contributing today was on 2-Butoxyethanol's environmental effects. I was also looking to provide some information on how it moves through the environment. I don't know if that helps you to understand the intentions behind my contribution, but if you need more help I could try to provide it. Custodim (talk) 01:09, 13 March 2014 (UTC)

It just seems that what you are trying to do requires a lot of expertise in biosynthetic and biodegradation pathways and access to high level sources, not just websites. So I would try to convince your teacher to get involved (probably over their head too, I would guess) or make the topic a little easier. Also, Misplaced Pages is an encyclopedia for rather general knowledge, not a catalogue of articles and websites. I hope that my advice does not seem harsh, but it seems that your assignment is almost too high and too vague. --Smokefoot (talk) 17:48, 13 March 2014 (UTC)

In re your comments at my Talk page

Smokefoot writes: Just a couple of comments/suggestions. Rather than critiquing - edit! That is what we do here. It takes less effort to consult a monograph or text on conformational analysis or VSEPR and repair something amiss vs writing "nearly all of the article is unverifiable, and parts are inaccurate or indecipherable, and so therefore are unreliable as encyclopedic content.". Start by editing in dribs and drabs. Target the worst parts of offending articles. A lot of this stuff is written by non-experts, so there is no problem with experts apparently like yourself just rewriting/deleting a section or two and then waiting to see how the revision is received. Typically deafening silence. The chemically fluent editors are helpful but tend to mildly avoid each other, not out of antisocial tendencies but because our interests diverge. FYI, IMHO the greatest long range challenge in Wikichem is WP:UNDUE, which arises from WP:COI and non-observance of WP:SECONDARY. Happy editing, --Smokefoot (talk) 23:40, 30 May 2014 (UTC)

Au contraire, many types of activities are occurring here, and some editors do no original content generation, and are quite content (and well regarded for their "contributions"). In re: "It takes less effort…"

I dont know of any "effective" contributor who just critiques, but maybe that is your niche. Misplaced Pages takes all types.

Again, to the contrary, one of the problems of this organization is the very low view that is taken of adequately understanding and crafting and sourcing content before posting—in large part, because just typing, and later proof-texting is so easy, relative to true, solid content generation.

well, a lot of early Wiki-chem was written by authors winging it. But that material is slowly being revised into more ground content. For example, there are not many compositions of matter described here in a misleading way. The more problematic articles are on concepts.

No, to create de novo or to fix to comparable quality of a de novo creation—these are truly much harder than just calling attention to shortcomings. (This could have been your persuasive argument, that I have taken too easy of a tack.) So I do 70-80% of the former (de novo content generation), and 20-30% of the latter (calling attention, and there, it is usually a result of reviewing links outside of the article I am generating). So I am quite comfortable, philosophically and practically with this. (Professors are paid for critical thinking and discourse. As for impact, Martin Luther did not personally reform Catholicism from within, but there is no gainsaying his impact on the history of that institution, achieved via calling attention to matters needing to change—clearly, and firmly.)

Well that is a possible accusation: critiquers are to some extent taking the easy road (at the risk of alientation from appearance of pretentiousness or effeteness). An intermediate path exists, which involves revising the really awful stuff and adding attribution to a solid text or review.

BTW, It can be a huge effort to revise an article on, say, cyclohexane conformation. Before undertaking such a project you need to assess if Cyclohexane conformation is the most effective or appropriate article for the topic. All sorts of ill-thought out overlapping topics have often been created on very similar topics. It is this level of analysis that really is taxing. Often the solution is to merge related articles, which I sometimes advocate, thinking that a few good articles are better than a lot of bad ones. I have however become convinced that what makes Misplaced Pages special is its accommodation all kinds of specialized stuff.

Otherwise, I am quite comfortable with my approach to offering accolades for good content creation, editing and administration (and those doing it), as well as in challenging unfit material, and interacting with others (non-expert and expert), etc. Moreover, I have been awarded for calling attention to major thrusts of editing before the actual editing is done. This strategy has been, relatively speaking, so successful that I always post a talk section before doing any major edit. (On the other hand, the more common, opposite strategy, to edit boldly and wait for reversion, has led to reversion wars—once for taking out unreferenced material, and once for not taking it out—so you will forgive if I kindly assent to "agree to disagree" on this matter.

Well, there you go. Perhaps your new reviewer style is the way to go. The question is who better than you will address the problems you raise?

Some editors focus on really specialized academic stuff vs contextualizing (or they dont know any context). Often this problem comes from COI. Academics - high level and grad students - come to Misplaced Pages to highlight their papers. More difficult to control are extremely specialized articles created, probably, for some COI-driven process. These editors almost never contribute more broadly. They are here to showcase their sub-subfield.

But if you are another thoughtful subject matter expert, I am sure we will enjoy working together toward high quality, secondary-referenced scientific content, side by side (even though I am non-wikipedian in my approach) Cheers. Le Prof Leprof 7272 (talk) 00:17, 31 May 2014 (UTC)

Thank you for your message. It is a synonym of Commodity chemicals. I have created the redirect now. --Daniele Pugliesi (talk) 18:21, 16 June 2014 (UTC)

ooookay, where is the list of "commodity chemical" defined. --Smokefoot (talk) 18:24, 16 June 2014 (UTC)

In the page Commodity chemicals. However I am looking know to find some source and it looks that there is a little confusion about these terms. Furthermore, looking this Italian page it looks like that there are two types of commodity chemicals, so now I am not sure that the terms "bulk chemicals" and "commodity chemicals" are exact synonyms: most likely "bulk chemical" is a synonym of "branded commodity chemicals". Give a couple of days to check these definitions in a reliable source; in the meantime you can put some notice in the category to advice (maybe template:WIP?) that I am checking this category. If I found some good source, I would create two similar categories for speciality chemicals and fine chemicals. --Daniele Pugliesi (talk) 18:33, 16 June 2014 (UTC)

Sounds like OR to me. --Smokefoot (talk) 18:38, 16 June 2014 (UTC)

I am going to create a page called "commercial classification of chemicals" or "industrial classification of chemicals" (see User:Daniele Pugliesi/Sandbox/2); in the case it will be too short, it can be incorporated in Chemical substance or Chemical industry. During the creation of this page/section I will check the meaning of each term in some reliable source. In the case of "bulk materials", I found this term somewhere (I don't remember where at the moment) as a synonym of "commodity", but now I am doubting that they are synonyms, so what do you suggest about the Category:Bulk chemicals? It is fine to leave it there another couple of days and in the meantime I check it, or it is better to delete it and decide after about its creation? Do you have any other suggestion/comment about the commercial classification of chemicals? --Daniele Pugliesi (talk) 19:04, 16 June 2014 (UTC)

Although with best of intentions, you may be engaged in a tricky game especially since you are starting this process before you have good sources. Yes, we realize that some compounds are made on a large scale. I recommend caution because I doubt if official definitions exist for bulk, commodity, or specialty. Related to petrochemical and petroleum products, you might want to start a category on one of those reasonably well defined labels. Good luck, --Smokefoot (talk) 19:45, 16 June 2014 (UTC)

I am translating it:Classificazione commerciale dei prodotti chimici, where there are enough sources about the definition of "commodity chemicals" and a clear (I think) explanation of its meaning. I am going to create also a table with the worldwide production of these chemicals: in fact one peculiarity of commodity chemicals is their high production. --Daniele Pugliesi (talk) 16:00, 29 June 2014 (UTC)

Well the main thing is that it is nice that you want to contributie. One suggestion if you are a new editor is to work on smaller scale projects than some grand mechanism.

Question: if you dont know enough basic organometallic chemistry to avoid these easy errors, why are you pressing to create images for the world to see? --Smokefoot (talk) 13:29, 8 July 2014 (UTC)

Fair question, friend. My goal was not to add knowledge to Misplaced Pages, my goal was to redraw mechanisms or schemes from WP that could look better with a little forethought into design. It started on Twitter as #ChemDrawChallenge, where we would take a sloppy or confusing ChemDraw image from a paper or from Misplaced Pages and redraw it with design in mind. Not change it or modify it at all, just redraw it. This image came from our third or fourth #ChemDrawChallenge and I liked it enough to replace the one on Misplaced Pages. Again, I had no intention of changing the mechanism, just recreating it. So while I am a Ph.D. organic chemist, and it's true I don't have the trained eye of an organometallic chemist and didn't see the basic errors, the question behind your question is how did that original mechanism last so long on the WP page if it suffers from the same basic organometallic errors?

But even that question doesn't really matter. My question is, is the original mechanism nice to look at? Could it be more clear or more appealing with a little face lift? And if it has errors, can we both fix those errors and make it more aesthetically pleasing and/or even clearer than the original? Is that structure in the original on the bottom right labeled 'Unfavored TS' clear and easy to read? I'm not necessarily saying my drawing was clearer (I hope it was, that was my goal), but the point was not to add knowledge, but to add aesthetics. I wish I had the ability to correct the errors and make it more appealing, but I did not. Let's work together to accomplish both goals. --Azmanam (talk) 19:51, 8 July 2014 (UTC)

Photographic film edits

To my eyes, "... creates an invisible latent image in the emulsion, which can ..." said just the same thing as "... creates an latent image in the emulsion. Although invisible to the eye, this latent image can ...", but in fewer words and perhaps a bit more clearly because of it.

My understanding of WP guidelines is that the lead is supposed to be concise and written in terms that are as non-technical and accessible to the general reader as possible, which also throws into question the wisdom of reiterating the basic concept of a "slight chemical change" as an "incipient chemical reaction", a more dauntingly technical albeit more specific description that may be counterproductive detail in this context.

:I was trying to remove jargon or explain it a little better, but you seem to have a good way of writing, so I am cool.

A link to the broader topic of photographic processing rather than to photographic developer seems more likely to be helpful to the uninitiated -- and development alone will not produce the "visible and permanent image" subsequently promised by the new wording without the fixing step that is an integral part of the former article's subject.

:I will look at photographic processing. Photographic developer seems redundant, rambling, and seems to be hankering to give advice. I might re-write it more concisely.

Finally, a beef which is not my own but which I am inclined to take to heart. Another editor has ranted with evident exasperation that the image, strictly speaking, is what the camera lens projects onto the photosensitive surface; the resulting artifact is a photograph of an image, not an image. The lens of the eye projects an image of the photograph onto the retina. Common usage rarely makes that distinction -- even collectors of vintage photographs usually call their swap meets "image shows" -- so it is certainly not mandated here, but when possible without making the wording too awkward I now incline to referring to the artifacts themselves as "photographs" rather than "images". Therefore, the former "... visible photograph" seems preferable to "... visible and permanent image, the photograph" for multiple reasons. AVarchaeologist (talk) 23:19, 6 July 2014 (UTC)

:Well that kind of thinking can drive one nuts. Not sure it serves our readers. Please let me know how or where I can help. --Smokefoot (talk) 00:23, 7 July 2014 (UTC)

Fertilizer page

Thanks for your contribution; I have been chipping away at some of the details, but I agree that major changes in structure are necessary; use of the term "organic fertilizer" also needs to be tightened up - See Talk:Fertilizer

Regarding your comments about Cracking (chemistry) on my Talk page

Hi, Smokefoot: In general, I would agree with your comments. However, as I am now almost 92 years old and also that I have not had anything to do with the subject article, I hesitate to get involved in re-writing parts of that article. Please try to get some chemist (rather than a chemical engineer) to get involved. mbeychok (talk) 17:54, 9 August 2014 (UTC)

Re: chemistry articles

I've read your comment (message?) on my page. I understand what you mean, but I was just adding some info that could not be found anywhere else and I once needed, and couldn't find on wiki. Anyway, I'll refrain from adding manual-like content (pretty much the only stuff I can add, sadly). It's better being told right at the beginning then after writing a lot. Valeg96 (talk) 12:24, 15 August 2014 (UTC)

I'm replying here because this whole talk thing seems a bit complicated (it says if I reply on my talk you won't have notifications?) and I don't have time to take a full tour of everything. What has been amended/removed, just to know? Something else other than the H₃PO₄ synthesis? Valeg96 (talk) 14:33, 15 August 2014 (UTC)

Yes, I amended your edit on MnO. You can always check the history of edits by clicking on the history tab at the top of your page. Or you can check up on the editing activity of anyone by clicking "User contributions" on the left side of any user page. So if you look at my contributions, about ten entries ago, I made a big edit on manganese(II) oxide. And then you can see that today, inspired by your contributions, I edited iron(II) oxide. --Smokefoot (talk) 17:30, 15 August 2014 (UTC)

PTFE - "low resistance against flowing liquid"

I have just removed (from the article about PTFE) the following paragraph:

Another major application is in fuel and hydraulic lines, due to PTFE's low resistance against flowing liquids. Colder temperatures at high altitudes cause these fluids to flow more slowly. Coating the lines's interior surfaces with low-resistance PTFE helps to compensate by allowing the liquids to move more easily.

I wrote the detailed justification at the talk page of this article: Talk:Polytetrafluoroethylene#Low resistance against flowing liquid ???. Interestingly, there was a citation attributing this false statement to Ullmann's Encyclopedia of Industrial Chemistry (doi:10.1002/14356007.a11_393) and it was you, who added this reference by this edition:http://en.wikipedia.org/search/?title=Polytetrafluoroethylene&diff=prev&oldid=591314363 . The statement itself was added long time before by an anonymous user, without any citation. Could you please explain what exactly have you found in this Ullmann's Encyclopedia about "low resistance against flowing liquids"? As a PhD in physical chemistry and physics I am sure, that there must be some misunderstanding, but I do not have this book nor the access to its electronic version. Tescobar (talk) 17:24, 2 September 2014 (UTC)

Thanks for the diligence. Perhaps we should rephrase that statement. here are some quotes

"Uses

About half of the PTFE resin that is produced is used for electrical purposes …”

... Other important uses of PTFE resin are found in fluid-conveying systems, where it is used for gaskets, molded packings and seals, piston rings, bellows, overbraided hose, and lined pipe." --Smokefoot (talk) 23:51, 2 September 2014 (UTC)

Have a look?

File:Methylammonium.png

Due to a number of (new in the last couple years) to this class of compounds, and some odd redirects (methylammonium chloride -> methyamine) I believe it would be worthwhile to document the following materials:

• Methylammonium iodide
• Methylammonium chloride
• Methylammonium bromide

Because they're increasingly mentioned in the literature on solar cells. There's limited information out there about melting points &c, but the compounds are all "known" to pubchem, chemspider, SMILES, etc. Likewise the old literature (mostly crystallographic) is of interest to the Xray crystallographers, and the new data is interesting to the solar cell crowd. Rather than add three pages (there is no substantial mention of the fluoride) I thought a category page ala acyl halide and hydrogen halide might be worthwhile, so I took a stab at it in my sandbox:

• Methylammonium halide

Would you kindly have a look and see if you think it's adequate to add? Follow up on my talk page if you will. If nothing else, now there's an image file for the methylammonium ion. Riventree (talk) 23:24, 9 September 2014 (UTC)

Hi Riventree, great idea in my opinion. I bet these salts are used in all sorts of ways. It would be interesting to describe the structures with respect to hydrogen-bonding. Also whether these salts form hydrates. But that content can be added over time and eventually various editors will find some review on this area. I have also heard about various quat-PbI₃-based perovskites. Here is a drawing you might want to use for the chemboxes:

Heme Carbon Monoxide / Cyanide binding

You reverted my addition to the Heme article that CO and CN- bind the iron center in heme, which is responsible for carbon monoxide poisoning and cyanide poisoning. Both attach to heme ligands, but in different enzymes. CO poisoning binds more to hemoglobin and partially to cytochrome c oxidase. CN poisoning binds more to mitochondrial cytochrome c oxidase but also to hemoglobin, preventing uptake of oxygen. Both Hemoglobin and Cytochrome c oxidase rely on temporary binding of oxygen. Hemoglobin so it can carry oxygen to cells, and cytochrome c oxidase to convert oxygen into water. Hemoglobin + CO --> Carboxyhemoglobin. Hemoglobin + CN --> Cyanohemoglobin. Binding of CO or CN to a heme molecule prevents oxygen from binding. The same mechanism prevents both enzymes from functioning correctly. — Preceding unsigned comment added by Zuloo37 (talk • contribs) 22:58, 12 October 2014 (UTC)

Your enthusiasm is admirable, and you know a lot of chemistry, but it is still worth exploring your proposed edits on Talk pages before inserting them. You arent required to, of course, but it would be a good idea to give you a chance to hear different perspectives. Most of these articles already mention the affinity of heme proteins for these ligands. The lethality of cyanide is according to my understanding completely attributable to the electron transfer chain being shut down, not hemoglobin or myoglobin getting hit. Although now I see that even cyanide poisoning lacks a decent reference. Also, these kinds of assertions benefit from reference to a textbook or a review. I any case I will revert by reversions and give us both some time to get this sorted out with some nice solid refs. Hows that? --Smokefoot (talk) 02:56, 13 October 2014 (UTC)

C-H activation page

Thanks for the suggestions to the page, but I disagree with some of them. Including numbers in figures (not artwork) is found in scientific journals, and is easier to understand. This page is for the public in the end. The figures I have added follow those from journals and are cited. There is active research for developing new methods for C-H activation as well as using available methods, so I'm not being "gullible". The slides are cited, what's the issue with that? You can find them on google. I'm still fixing up the page, adding explanations, more examples and am reworking the page entirely. Thanks, Sarmalkow (talk) 05:42, 3 December 2014 (UTC)

Two points. First, thanks for the message and second, Misplaced Pages has guidelines, which you are encourage to learn a little about.

First of all, yYou dont own the article. See Misplaced Pages:Ownership of articles. We all edit each others work all the time. Routine. And experience shows that students homework assignments could almost alway be improved - do you agree? Some specifics: The term "recent" becomes stale in a year or two in the encyclopedia, no one is using Periana catalysis for methane activation. Ever. Why refer to him with a title Prof? etc. We prefer to avoid words in artwork. You are not writing for the US only, what if other language Wikis want to use the art? they are stuck with the English in many schemes. Yes, journals do that but they also copyright their artwork, Misplaced Pages does the reverse, we share our artwork. For many Wiki readers, English is not their language of choice. See this Misplaced Pages:Manual of Style/Chemistry#Reactions.--Smokefoot (talk) 15:00, 3 December 2014 (UTC)

I know that WP is public and anyone can edit any article. I don't need a lecture on that. How is a student homework assignment relevant? "Recent" is relative. Periana catalysis was in the article previously; I just moved it into a different section. Even if it isn't used anymore, it still provides context. The prof title was in the article previously. What words in the FIGURE (it's not artwork)? Guided and Innate? It lends to making the content more digestible, or that's what I understand (look at the article, they do it). I'm not writing for just those that read English, yes, but two or three words in a figure doesn't ruin it. You can say the same about color; color in a figure isn't helpful for those who are color-blind. WP is for the public, including those that aren't familiar with the subject. Hence, removing introductory information to contextualize an idea isn't conducive toward achieving that goal. Oh, and removing the figure from reaction conditions...that figure has been on the page forever. I'm still adding to the page. Also, if you're going to talk to users, take the time to check your spelling and grammar.Sarmalkow (talk) 19:05, 3 December 2014 (UTC)

I'll address one point: use of numbers to identify structures in an image. The fundamental problem is that it ties the image to the article at the point it was created. The image becomes less usable in other contexts. And the article itself becomes less editable because if the images get shuffled around the numbers get out of sequence. And if new images are created, they need to sync with the same numbers previously used for each compound. For example, there's no need to put any number in "File:Steric Effects Figure 1.png" because it's the only structure there and there is no other use of it elsewhere in the article--one can just say "the image above".

Okay, I find I'm headed into some other points...The experimental results (specific catalysts and their product ratios) can similarly be removed and simply described in the text (since it really is just text anyway). Or simply omitted altogether (Misplaced Pages focuses on secondary references, so seeing this specific set of primary data is possibly too detailed). Even the filenames such as that one's emphasize how tied to "the current writing of the current article" it is rather than being a sharable image on a centralized server for an article that will evolve over time. DMacks (talk) 19:37, 3 December 2014 (UTC)

I guess I just find figures with numbered compounds helpful. I agree with the figure containing only one structure, but disagree when multiple structures are present. And if this is an issue, why do other pages contain words and numbering in figures? i.e. Cycloisomerization, Cieplak Effect, Wittig Reaction, Horner-Wadsworth-Emmons reaction. I was simply trying to improve a page in need. Sarmalkow (talk) 03:00, 4 December 2014 (UTC)

I know that two of those articles you mention were written from scratch (including the images) within the past few days by editors who also are new to Misplaced Pages. It's not unusual for new editors not to know the local style guidelines and conventions. Some of those are even worse in that the "Figure #" is part of the image itself, making the article highly resistant to any edit that would insert, remove, or re-order the images. I vaguely remember a discussion years ago generally disfavoring "Figure 1" and the like (not specific to chemistry articles) but I can't find it in the Manual of Style at the moment. DMacks (talk) 03:17, 4 December 2014 (UTC)

Sarmalkow, thanks for engaging us. This time of year, and again in the spring, Wiki-chem gets a burst of homework assignments, like yours. These students are trying to do the right thing but how could they possibly know the guidelines? Unfortunately, instructors are rarely involved and also do not know Wiki-guidelines. U.S. students especially seem rarely mindful that Misplaced Pages is highly international, with the consequence that artwork can be shared over many languages, hence our encouragement that you edit your ChemDraws. Another characteristic of homeworky projects is that rather than making incremental, integrated edits, which is the way Misplaced Pages tends to grow well, students drop a large and often self-standing essay that does not integrate well (like your compound numbers) into our exsiting content. Understandably: students are looking for a grade and they are rarely going to come back to Misplaced Pages and "clean up after themselves." So now you know some perspectives, we wish other students did the same, but you got picked on and your classmates did not. Let us know if we can help. One way you can help is to pass on this advice to your instructor! --Smokefoot (talk) 03:38, 4 December 2014 (UTC)

Shouldn't we be grateful that information is added? It helps everyone out. I think the approach to familiarizing new editors is just a little harsh. New editors are just trying to help, like seasoned editors. Thanks for the insight. Sarmalkow (talk) 04:37, 4 December 2014 (UTC)

Yes, we are being a little harsh, or actually frank. Misplaced Pages is the recipient for a lot of homework, all well intentioned, maybe slightly naive.... So what we are trying to say is that with a little tweaking, your (and your fellow students') contributions could much more helpful. But point made about rule, harshness, my bad spelling, etc. Good luck. --Smokefoot (talk) 05:01, 4 December 2014 (UTC)

I also agree with the "thanks for contributing" and the value added by even good content that is not up to great style. And I also echo the need to get feedback back to the instructors about how they can better work with Misplaced Pages and help their students understand/become more quickly accustomed to the nature of Misplaced Pages.

removal of See Also links on EDTA page

Hi, I understand you may not be familiar with the preservatives used in ocular pharmaceuticals, but it would have been polite for you to follow up with me (or any online source) to educate yourself first, rather than just reverting my edit. WitheredLimb (talk) 03:02, 9 December 2014 (UTC)

Oh thanks for the note and sorry to have behaved impolitely. I saw that someone else deleted your see also link. For the EDTA article, if we made a see also link to every app of this common chemical, it seems that the list would be quite long, dont you think? --Smokefoot (talk) 04:51, 9 December 2014 (UTC)

They weren't apps you deleted, they were alternate preservatives to EDTA used in ocular pharm. Increasingly EDTA is used instead of BAC, so I have added EDTA to BAC page (as well as other 3rd gen and 1st gen preservatives). For completeness they were also added to EDTA page. Don't see an issue with listing alternatives - there actually aren't that many. Am getting used to my edits being reverted. Think I might be in the wrong place here. — Preceding unsigned comment added by WitheredLimb (talk • contribs) 05:06, 9 December 2014 (UTC)

You are definitely not in the wrong place. And I can be an aggressive editor. So the collision of your relative inexperience with my ways is surely frustrating. You handled the situation perfectly: with a note to the deleter. The other angle you can take is, if you think my action was ill-advised, is revert what I did with some comment (explanatory or semi-snark).

I avoid giving advice because I am no guru, but here goes. We all get absorbed in our specialties and are keen to share our hard-won insights. The problem is that our pet knowledge (mine too) is often rather specialized. But then our edits run the risk of violating this guideline WP:INDISCRIMINATE. --Smokefoot (talk) 06:10, 9 December 2014 (UTC)

Zinc phosphide

Thanks for that. Never come across zinc phosphides before - so quite interesting- a semiconducting rodenticide no less. The coordination of Zn in Zn₃P₂ is approx tetrahedral, P is 6. A bit weird- the structure is sort of fluorite like but as not all T holes are filled the coordination is 6 of the vertices of a distorted cube. ZnP2 has infinite P chains- anions if you like limiting ionic structures although its a semiconductor too. The structure images we put up in wikipedia do not always do the coordination justice particularly when the coordinated atom is close to the edge of the unit cell. Regards.

UG contribs to WP

Hello Smokefoot

I know that you've been using students to contribute to WP for several years, and I was wondering about doing the same. We're just setting up a new course here at Bristol on the theme of Chemistry in the Digital age, and WP seems like a good topic, especially as that's now the default source for anything they want to know. Would you be able to give me a quick rundown of what you do with them / potential pitfalls / benefits?

Thanks,

Chris (talk) 12:32, 14 January 2015 (UTC)

I would be glad to help. First of all, we contribute through a course that is mainly a lab (synthetic inorganic/organometallics for advanced undergrads). This Misplaced Pages article is worth about 10%. Here are some aspects:

• I do ‘not emphasize Wiki-formatting'. This assigment focuses on teaching them to write about chemistry and learn how to copy-edit, not learn Misplaced Pages techniques (although they are free to do so, and many do). To this end, in the past few years, I have set up the articles, precluding their need to even register (I realize that Wiki-central command views student involvement as a recruiting mechanism but I have not seen that trend after going through hundreds of students). The skeleton articles that I establish, illustrate referencing, chem box, linking. You can see this approach with the history of iron boride. Similarly, we have shifted increasingly to article improvement, again avoiding their need to register) as illustrated by lead styphnate.
• We try to write shorter articles and this is probably our greatest weakness compared to typical multi-page student essays where they learn a lot about a big area. The emphasis however is on editing as much as creating content.
• Students work in teams. I have about 30 students and supervising 30 articles is too much work to do well (in the past courses we have uploaded many more). Employers of my students want them to demonstrate an ability to work as teams. I am highly focused enhancing student employability. Only a fraction are aiming for professional schools - and they tend to write on academic topics such as Transition metal alkyne complex, Nitrogen-15 NMR spectroscopy.
• Students must get their draft article approved by me as a Word document before they can upload to Misplaced Pages. It is refining this Word document where they actually learn the most and where I do most of my work - about 2-3 drafts.
• I de-emphasize graphics. Probably nonideal, but students are not very good at ChemDraw and I am picky. We could do more at pdb and csd images, but again this aspect of the course emphasizes writing not drawing.
• We spend a lot of time figuring out topics. For some appealing topics we just cannot find good general sources, so we dont pursue those. We are increasingly turning toward improving existing articles because we are running out of topics and so many existing articles could use help in select themes.
• Although the course is on inorganic/organometallics, I figure that for undergrads just learning to write about any chemistry is healthy, so we write about all sorts of topics. I also meet with them to identify their professional interests, the point being that articles might enhance their employment aspirations and hence their devotion to their topic. Some of their diverse interests have been in beer brewing (see Humulone), perfumery (2-Methylundecanal), pesticides (Pentachloronitrobenzene), antibiotics (Yersiniabactin), explosives (lead styphnate). These are employable topics in the US. Naturally, they write a lot of inorganicky articles too, which are not coupled to employment.
• I prohibit students from discussing tox or safety or environmental aspects, despite the fact that I am a tree-hugger myself. Googling on chemical topics mainly turns up tox - safety - environmental content, often crufty, but I want them to write about hard core chemistry. Students are always ready to fill any article with all sorts of health and safety stuff - easy to get and easy to write about, but not very chemical (unless they figure out the chemical mechanism of tox, etc).

My edit to 1, 1, 1-Trichloroethane

Why did you revert my edit? The words "dicarbon trihyrdogen trichloride" would actually be its chemical name using the correct systems. DudeWithAFeud (talk) 02:08, 22 January 2015 (UTC)

No problem. People dont use that name. Its not a big deal.--Smokefoot (talk) 03:03, 22 January 2015 (UTC)

The appellation "dicarbon trihyrdogen trichloride" does not specify where the chlorine atoms are located in the molecule. The 1,1,1- prefix specifies the three chlorines are located on the #1 carbon atom. The isomer 1,1,2-trichloroethane is also possible. 1,2,2-trichloroethane is the same as the 1,1,2- and so the lowest numbering is used. Similarly, 2,2,2- is the same as 1,1,1- and again the lowest numbering is used. The hydrogens are understood to be placed on the carbon skeleton as needed wherever there are no substitutions. According to the IUPAC naming system (IUPAC claims its naming system is the official one.), 1,1,1-trichloroethane is used. H Padleckas (talk) 06:23, 23 January 2015 (UTC)

... and again, people dont use that kind of name/appellation no matter how many numbers one puts before or after it!--Smokefoot (talk) 12:42, 23 January 2015 (UTC)

Thanks for help, Smokefoot and welcome to my new semester

Hi Smokefoot- thanks for dropping by my course page and giving advice on chemical pages. We haven't chosen our topics yet, although I imagine some chemical pages may be in for some work by my class. I read the thread you recommended, and don't believe my students have been guilty of dropping entire essays into the midst of existing pages. We focus on developing tight paragraphs of information to add to stubs or start class articles. Let me know if and feel free to jump in, of course, if you notice one of mine not following the chemistry rules. I'm fully connected with the Education Foundation (trouble keeping up with the name), used their new page wizard (nice!), and have a couple of them helping out with class. Hakeleh (talk) 01:40, 7 February 2015 (UTC)

@Hakeleh: , the main thing is thanks for the response. The greatest problem Wiki chem has with homework projects is that the students get in over their heads and the instructor is missing in action. The result is that the student insert newsy or narrow Google-able citations in order to meet some quota. I am sympathetic that it is difficult to select areas in Misplaced Pages where broad, not narrow information is missing. If you look at Education Program:Louisiana State University/CHEM 4150 Environmental Chemistry (Fall 2014), students added low quality content on poorly conceived topics. All of those students contributions were wiped clean from Misplaced Pages, I recall. I have taught many courses using Misplaced Pages as a component, and it is a fair bit of work, expecially topic selection and guiding sourcing. Good luck because I know this is hard work, --Smokefoot (talk) 14:20, 7 February 2015 (UTC)

@Smokefoot: Hi Again, Smokefoot. We've chosen many different chemistry pages to work through this semester, and I see that you've visited most of them. Its great for the students to know that they are connecting with a very large community of Wikipedians. Several Wikipedians have worked with my courses over the past several years, and our contributions to Misplaced Pages have been improved, and the student's experience enhanced. I invite you to spend some time looking at the contributions made through my courses Hakeleh. Unfortunately, thus far, our experience working with you has been very disappointing. I'm referring to the many very insulting comments you have made in response to my student's initial postings on the talk pages of the articles they are beginning to work on. For example: 'When you say "different chemicals that are polymerized" you sound chemically illiterate. It will be difficult for someone with such a weak grasp of our language to contribute useful content?' This was your response to someone's comment on an article TALK page. This is insulting on so many levels, I can't even begin to list them. Also, on many article talk pages, you left a statement like this "Please talk to your teacher about how grown-ups do bibliographic searches in the sciences." I feel condescended to and nervous about contributing further to wikipedia from reading this comment, and I can only imagine what a young adult would feel when faced with this type of 'input'. A key component of this type of assignment, as you likely know, is training in how to find good sources. We've been doing that. The bibliographies listed on the article talk pages are the initial sets of references, and many may not even be included/ used in the article improvements that end up on the main article page. In response to the 'grown up' comment from you one student spent time investigating the list of references YOU added in response to their bibliography and found that, in contrast to the list of sources they listed, your list included sources that were unavailable and that had in fact already been eliminated from the list of sources they will use for the WP entry. This example brings up another very important point: the amount of my time and my student's time that has been used toward reacting to and responding to your input. This is time that could have been much more productively used by all of us to do what we want to do, which in this case is to improve Misplaced Pages entries. If you feel that my student's contributions to the main article pages are not up to par, we welcome your constructive input. If you feel compelled to add demeaning and insulting comments to their entries, please first contact me with your complaint and I will work on constructively addressing any and all issues with my students. Also, we are currently following the plan for developing Misplaced Pages entries developed by the Wiki Education Foundation, which includes listing potential references and a contribution plan on the article talk page. If you have issues with this format for student contributions, please discuss it with them.

Thanks for the input. In my experience many or most courses contribute bad content to Misplaced Pages-chemistry: where students focus on word count, who seem to have little instruction on searching (Googleable, US-centric), and whose work gets little intervention by the instructor. Furthermore, I do think that comments like "different chemicals that are polymerized" is distinctly unpromising for would-be editors at Misplaced Pages. For an in class essay, that level of awkwardness about "chemicals" is fine, so I wanted to loudly warn them that the standards are higher if they intend to contribute at Misplaced Pages. I also reminded them repeatedly not to go after these compounds as if they are evil, which has been a pattern previously.

Obviously, these are my views, which you may not share and, to some extent, find very offensive. I saw no other way to get their attention. And even with my semi-shrill comments, we almost never see expected responses from these students who supposedly are reaching out on the talk pages. Obviously they are not reaching out, but simply blurting out statements of what they will do, whereas editors here expect cooperation, consensus, and conversation over plans. I and others were expecting responses from the students like "Got it, we are just learning how to use Web of Science" or "We are cognizant of WP:MEDRS" or "Thank you for suggesting reviews that we had not considered, but why don't you think our sources are not as good?" or "You're right, we were being too US-centric."

Finally, you can however also see that rather than simply complaining, I on several occasions suggested some good reviews for the students to build on. Those reviews are the foundations of their content. In any case, good luck, --Smokefoot (talk) 19:33, 25 February 2015 (UTC)

Organic Semiconductor notability

Why do you think the device created by Dr. Peter Proctor and Dr. McGiness was not significant? If there is an organic semiconductor device that was developed before theirs show its picture and WP:UNDUE goes away. I learned about the switch from the Smithsonian chips collection. Are you suggesting the Smithsonian institution is not reliable? Although it could be, the article by McGinness, Proctor and Peter Corry "Amorphous semiconductor switching in melanins." Science 183.4127 (1974): 853-855. has been cited 312 times since its publication in 1974 http://www.sciencemag.org/content/183/4127/853.short. That article documents the work which led to the device's creation.

Citations for the above article. https://scholar.google.com/scholar?cites=205685824019020802&as_sdt=20005&sciodt=0,9&hl=en — Preceding unsigned comment added by Mhotep (talk • contribs) 17:49, 7 February 2015 (UTC)

I can see where you are coming from, and I really appreciate the note. Two things on my mind

• 1) Proctor was a major fraudster and bully on Misplaced Pages, who turns out to be an embittered quack who sells hair-growth cures. He promoted this device insufferably (there must have been 6 copies of this image across Misplaced Pages). The article on McGiness exists only because of his student Proctor's efforts . McGiness was an ordinary scientist who published a nice paper. See John McGinness. If McGinness contribution were notable, he would have been recognized professionally with awards and such (academicians are very good at decorating each other). None of the extensive Nobel literature (reviews by the three prize winners) even mentions McGinness contribution.
• 2) To most researchers and technologists, "organic semiconductor" means a well defined synthetic material. The revolution in organic semiconductor area was the preparation of well defined materials that enabled structure- property correlations. These innovations led to a Nobel Prize to Kitagawa et al., which motivated then editor Proctor to wage a belligerent campaign on any Misplaced Pages article that praised the achievements of these Nobelists. Hints of his efforts remain in the organic semiconductor article, Proctor's point being that everything the Nobelists were recognized for was done well before them. It is disappointing to me that readers who do not know a lot about the field will the impression that McGinness's contribution was important or that doped melanin is representative of the well defined materials that captured the imagination of the world when Kitagawa et al announced polyacetylene.

In any case, that is my 2 cents. Best wishes, --Smokefoot (talk) 21:58, 7 February 2015 (UTC)

undo revision on photobleaching page

I agree that the paragraph you removed was too arcane for the article. However, I do think that the greater point (that there are various strategies to improve photostability) is important for the article, and that the citation should be kept. Richard☺Decal (talk) 23:24, 9 February 2015 (UTC)

Hi and many thanks for the note. I am pretty distracted now to think about this but will do so probably on the weekend. Misplaced Pages is dealing with a lot of unsupervised students being forced to add content for Misplaced Pages, and I can be a little too hasty in my edits of their contributions, which are usually not very good.

Methyl formate

Smokefoot, first off, I am new to Misplaced Pages, so I apologize in advance for any errors in etiquette. I saw your edit to mine on methyl formate and wanted to discuss, rather than go back and forth in dueling edits. I did not add the reference to Foam Supplies and Ecomate, but just wanted to clarify that Foam Supplies holds the patent on using methyl formate as a polyurethane foam blowing agent (trade name Ecomate)...and also add that PU foam is used for more than just insulation. I guess this could be considered "commercial", but it is factual and I think relevant (just as BASF is mentioned right above as a producer of methyl formate).

One thing that I do feel is misleading in your edit is to say that methyl formate "has also been considered" as a blowing agent...since it has been in commercial use as a foam blowing agent since 2002. Here is reference showing it has been EPA SNAP approved since 2003: http://www.gpo.gov/fdsys/pkg/FR-2003-08-21/html/03-21425.htm

Again, I am new to this and hope this is the right approach to take.

DrGeorge888 (talk) 21:11, 23 February 2015 (UTC)

Well the main thing is thank you for your time and consideration. It is usually very irritating to have one's work mangled or modified. Go ahead and revert my edit. I assumed that you were pushing a commercial item, and we are very leery of that kind of activity. A large fraction of edits from newcomers is solely to support some cause of theirs, Happy editing and, since we now know each other, feel free to ask other questions. Happy editing. --Smokefoot (talk) 23:47, 23 February 2015 (UTC)

Thanks! It's good to know that someone is "policing" these articles from purely commercial messages. DrGeorge888 (talk) 13:55, 24 February 2015 (UTC)

Just saw your new edit, and I think you left out some words? What about something like the following? Because of its high vapor pressure, it is used for quick-drying finishes. Methyl formate is also used as a blowing agent for a wide range of polyurethane foam applications under the trade name Ecomate, patented by Foam Supplies, Inc., as a replacement for CFCs, HCFCs and HFCs due to its zero ozone depletion potential, zero global warming potential and zero volatile organic compounds. . It is also used as an insecticide. DrGeorge888 (talk) 15:31, 24 February 2015 (UTC)

YOu are welcome to re-edit. The reason it is a blowing agent is its volatility, and I was trying to unify that property into multiple uses. I was also trying very deliberately to avoid the term "Ecomate" which seems parochial (probably some US brand) and ephemeral (brand names come and go). The global warming bit sounds like a sale pitch to me, even if it is true. These are probably niche apps, the big kahuma being formic acid. My guess at least. --Smokefoot (talk) 22:11, 24 February 2015 (UTC)

Could you have a look at the last sentence in that paragraph?

You reverted my edit, which is fine. I am usually willing to defer to you in things like this. However, I believe that the explanation clearly shows the intent to separate the absorbtion of salt and then the lowering of pH. Only the latter would be the case if hydrochloric acid were the intended compound. If you concur, please revert your reversion.

Riventree (talk) 00:58, 1 March 2015 (UTC)

You seem to have thought about it, although it is possible that these old-timers or low-tech chemists are cheaply making HCl, but it doesnt really matter. Now about Rogalite ... You have my attention. Cheers, --Smokefoot (talk) 03:45, 1 March 2015 (UTC)

Rongalite smells like spam to me. Checking "What links here", I note that it's only referred to as "Rongalite" in a positive context, whereas the negative contexts have been converted to chemical terms (sodium formaldehyde sulfoxylate) which redirect to it. It's got a chemical data panel, but it's listed by a trademarked name. This is not the way we handle (for instance) Phisohex or Rohypnol. I suggest the page be moved to sodium formaldehyde sulfoxylate, and redirect from Rongalite.

For what it's worth, your phrase "You seem to have thought about it" is pretty rude. Yes, I actually read the paragraph I was editing, and actually thought about it before I changed something. I assure you that's how I normally proceed. On the other hand, you seem to have failed to do either before reverting my edit. Perhaps the shoe fits better on that (Smoke)foot.

Oh, I didn't intend my comment in a negative way. My speculation was that you had thought about the process so deeply to convince yourself to insert the temporal aspect when none was mentioned. I wouldnt have thought so deeply but would have taken the process description at face value. Oh well, its always curious how these off-hand remarks can get read when one would never draw that conclusion verbally.

About Rongalite, I encourage you to get that article renamed. It may be one of those terms like Kleenex that has just become generic. Ullmann's Encylopedia uses the term a lot. I would not draw any particular conclusions about the lack of negativism in its description. --Smokefoot (talk) 23:26, 1 March 2015 (UTC)

"Meaningful user page"

I have to say this edit is rather shocking from such an experienced user. I'm not sure where you got the idea that having anything at all on your userpage was even remotely a requirement for low-level user permisssions, but I can assure this is not the case and as far as I am aware never has been. And of course asking "who are you" is way, way out of line. Permisssions requests are about reviewing a users contributions to the encyclopedia, not who they are and what they choose to put on their userpage. In fact, in the hundreds and hundreds of permisssion requests I have personally reviewed I don't recall a single case where a userpage was relevant.

Frankly I think PERM doesn't really need extraneous comments at all, but it certainly doesn't need comments like that. Please don't make comments like that again, they do not help admins make decisions and only get in the way of what is supposed to be a fairly straightforward administrative process.

Well I definitely got that you are agitated. For those contributing technical content, it is very helpful to know something about the editor, at least for me, but apparently not for you. We all tend to read too much into little notes we leave around here, so dont let my opinions weigh on you. --Smokefoot (talk) 20:42, 15 March 2015 (UTC)

It's not that I'm agitated, it is that remarks like that one are unhelpful, get in the way of what should be a simple administrative decision, and are contrary to our policies. It may be your opinion that you need to ask such things, but I think you will find that pretty much nobody who works at PERM would agree with you and would instead find such comments an unwelcome and unhelpful obstruction. So please, don't do that again, regardless of your opinion on the merits of such questions. Beeblebrox (talk) 21:13, 15 March 2015 (UTC)

It was my intention to be helpful, not unhelpful. I was not trying to cosy up to the newish editor, but tell them what I thought. So, I am sorry that you and your colleagues are cross with me. If my well intentioned remark offended you or the editor, I extend my apologies. In the chemistry sphere of Misplaced Pages, which I mainly inhabit, editors with blank user pages as well as those unregistered are often problematic. If you want to get a sense of this pattern, look at the editing at water fluoridation, a technology that alarms a small but fierce group of opponents. You will see that the disruptive edits tend to come from those unregistered or with blank user pages. You must have noticed that pattern elsewhere. But hey, this thing is not that big a deal to me and since you seem to have a lot of experience, I will definitely think twice before suggesting to another editor that they say something about themselves or their intentions on their user pages. Thanks for taking the time to advise me. --Smokefoot (talk) 21:48, 15 March 2015 (UTC)
