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]
Infobox references. 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 ...
Hydrofluoroolefin. 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, HFOs are olefins, otherwise known as alkenes.
