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 ...
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 ...

It specialises in digital content, online entertainment, social networking, and e-commerce. [ 2] Its focus is on four main businesses, including online games ...
CHCl 2 CF 3: 2,2-Dichloro-1,1,1-trifluoroethane: 292 79 US phase-out Used in large tonnage centrifugal chiller applications. All U.S. production and import of virgin HCFCs will be phased out by 2030, with limited exceptions. [67] R-123 refrigerant was used to retrofit some chiller that used R-11 refrigerant Trichlorofluoromethane.
