==Properties==
The structure of trans-1,3,3,3-tetrafluoropropene was investigated both in the gas state (gas electron diffraction) and in the crystalline phase (X-ray diffraction). In the crystal, it aggregates via C-H---F contacts from 2.44(1) to 2.63(1) Å.<ref>Jan Schwabedissen, Timo Glodde, Yury V. Vishnevskiy, Hans‐Georg Stammler, Lukas Flierl, Andreas J. Kornath, Norbert W. Mitzel: Structures and Properties of trans ‐1,3,3,3‐Tetrafluoro‐ propene (HFO‐1234ze) and 2,3,3,3‐Tetrafluoropropene (HFO‐1234yf) Refrigerants. In: ChemistryOpen. Band 9, Nr. 9, September 2020, ISSN 2191-1363, S. 921–928, doi:10.1002/open.202000172</ref>
Combustion experiments with trans-1,3,3,3-tetrafluoropropene produce carbon dioxide, carbonyl fluoride and hydrogen fluoride as the main combustion products. The determination of the flammability range leads to the classification of trans-1,3,3,3-tetrafluoropropene as a highly flammable gas.

==Uses==
The increasing concerns about global warming and the related possible undesirable climate effects have led to an increasing agreement in developed countries for the reduction of greenhouse gas emissions. Given the relatively high global warming potential of most of the hydro-fluoro-carbons (HFCs), several actions are ongoing in different countries to reduce the use of these fluids. For example, the European Union's recent F-Gas regulation<ref>Regulation (EU) No 517/2014</ref> specifies the mandatory GWP values of the refrigerants to be used as working fluids in almost all air conditioners and refrigeration machines beginning in 2020.<ref name="giula">Giulia Righetti, Claudio Zilio, Simone Mancin & Giovanni A. Longo (2016): A review on in-tube two-phase heat transfer of hydro-fluoro-olefines refrigerants, Science and Technology for the Built Environment, DOI:10.1080/23744731.2016.1229528</ref>

Several types of possible replacement candidates have been proposed so far, both synthetic and natural. Among the synthetic options, hydro-fluoro-olefins (HFOs) are the ones appearing most promising thus far.

HFO-1234ze(E) has been adopted as a working fluid in chillers, heat pumps, and supermarket refrigeration systems.<ref>{{Cite journal |doi = 10.1016/j.ijrefrig.2013.08.013|title = Condensation of the low GWP refrigerant HFO1234ze(E) inside a Brazed Plate Heat Exchanger|journal = International Journal of Refrigeration|volume = 38|pages = 250–259|year = 2014|last1 = Longo|first1 = Giovanni A.|last2 = Zilio|first2 = Claudio|last3 = Righetti|first3 = Giulia|last4 = Brown|first4 = J.

It has been demonstrated that HFO-1234ze(E) can not be considered as a drop-in replacement of HFC-134a. In fact, from a thermodynamic point of view, it can be stated that:

– The theoretical coefficients of performance of HFO-1234ze(E) is slightly lower than HFC-134a;

– HFO-1234ze(E) has a different volumetric cooling capacity when compared to HFC-134a.

– HFO-1234ze(E) has saturation pressure drops higher than HFC-134a during two-phase heat transfer under the constraint of achieving the same heat transfer coefficient.<ref>Brown, J.S., C. Zilio, R. Brignoli, and A. Cavallini. 2013. Heat transfer and pressure drop penalization terms (exergy losses) during flow boiling of refrigerants. International Journal of Energy Research 37:1669–79.</ref>

So, from a technological point of view, modifications to the condenser and evaporator designs and to compressor displacement are needed to achieve the same cooling capacity and energetic performance of HFC-134a.<ref name="giula" />
