2,3,3,3-Tetrafluoropropene, HFO-1234yf, is a hydrofluoroolefin (HFO) with molecular formula CH 2 =CFCF 3. Its primary application is as a refrigerant with low global warming potential (GWP). [ 1][ 2] As a refrigerant, it is designated R-1234yf[ 1] and marketed under the names Opteon YF by Chemours and as Solstice YF by Honeywell. [ 3]
trans-1,3,3,3-Tetrafluoropropene (HFO-1234ze (E), R-1234ze (E)) is a hydrofluoroolefin. It was developed as a "fourth generation" refrigerant to replace fluids such as R-134a, as a blowing agent for foam and aerosol applications, and in air horns and gas dusters. [ 3] The use of R-134a is being phased out because of its high global warming ...
1,3,3,3-Tetrafluoropropene. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 1,3,3,3-Tetrafluoropropene is a hydrofluoroolefin which has two isomers: cis -1,3,3,3-tetrafluoropropene. trans -1,3,3,3-tetrafluoropropene, used as a refrigerant (R-1234ze (E).)
cis. -1,3,3,3-Tetrafluoropropene. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). cis-1,3,3,3-Tetrafluoropropene (HFO-1234ze (Z), R-1234ze (Z)) is a hydrofluoroolefin which has been considered for use as a refrigerant in high-temperature heat pumps.

Hydrofluoroolefin. Chemical structure of 1,3,3,3-tetrafluoropropene (HFO-1234ze) Hydrofluoroolefins (HFOs) are unsaturated organic compounds composed of hydrogen, fluorine and carbon. These organofluorine compounds are of interest as refrigerants. Unlike traditional hydrofluorocarbons (HFCs) and chlorofluorocarbons (CFCs), which are saturated ...
Pentafluoropropane. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 1,1,1,3,3-Pentafluoropropane ( HFC-245fa) is a hydrofluorocarbon is a colorless gas used primarily for closed-cell spray foam insulation. HFC-245fa is also known as pentafluoropropane and by its chemical name 1,1 ...
Infobox references. 1-Chloro-3,3,3-trifluoropropene (HFO-1233zd) is the unsaturated chlorofluorocarbon with the formula HClC=C (H)CF 3. The compound exists as E- ( cis-) and Z- ( trans-) isomers. The trans- isomer of this colorless gas is of interest as a more environmentally friendly (lower GWP; global warming potential) refrigerant in air ...
Refrigerant. A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated because of their toxicity and flammability and the contribution of CFC and HCFC ...
