==Synthesis== |
|
|
NOBS is formed by the reaction of ] (or its ]s) with ] followed by ] using ] to form a ] at the para-position. |
|
|
|
|
|
==Bleach activation== |
|
|
NOBS was developed by ] in 1983<ref>{{cite book|last1=Chung|first1=S. Y.|last2=Spadini|first2=G. L.|title=US4412934|date=1983}}</ref> and was first used in American laundry detergents in 1988.<ref name="Cahn1994">{{cite book|author=Arno Cahn|title=Proceedings of the 3rd World Conference on Detergents: Global Perspectives|url=https://books.google.com/books?id=Pbr2HJ1X_DkC&pg=PA64|date=30 January 1994|publisher=The American Oil Chemists Society|isbn=978-0-935315-52-3|pages=64–70}}</ref> NOBS is the main bleach activator used in the U.S.A. and Japan.<ref name=Hirschen>{{cite book|last1=Hirschen|first1=M.|title=Handbook of Detergents Part C: Analysis|date=2005|publisher=Marcel Dekker|isbn=9780824703516|pages=439–470}}</ref> Compared to ], which is the predominant bleach activator used in Europe, NOBS is efficient at much lower temperatures. At 20 °C NOBS is 100 times more soluble than TAED in water.<ref name=Reinhardt1>{{cite book|last1=Reinhardt|first1=G.|last2=Borchers|first2=G.|title=Handbook of Detergents, Part E: Applications|date=2009|publisher=CRC Press|isbn=9781574447576}}</ref> |
|
|
When attacked by the perhydroxyl anion (from hydrogen peroxide), NOBS forms ] (a ]) and releases the leaving group sodium 4-hydroxybenzene sulfonate, which is an inert by-product. |
