摘要： A process is disclosed for making CF3CF═CHF. The process involves reacting CF3CClFCCl2F with H2 in a reaction zone in the presence of a catalyst to produce a product mixture comprising CF3CF═CHF. The catalyst has a catalytically effective amount of palladium supported on a support selected from the group consisting of alumina, fluorided alumina, aluminum fluoride and mixtures thereof and the mole ratio of H2 to CF3CClFCCl2F fed to the reaction zone is between about 1:1 and about 5:1. Also disclosed are azeotropic compositions of CF3CClFCCl2F and HF and azeotropic composition of CF3CHFCH2F and HF.

摘要： Refrigerant compositions including 2,3,3,3-tetrafluoropropene (HFO-1234yf) and at least one of ethane (R-170) or propane (R-290) which exhibit near-azeotropic or azeotrope-like behavior. The refrigerant compositions exhibit a low global warming potential (GWP) and are non-ozone depleting. The refrigerant compositions are useful as a heating or cooling fluids in a variety of heating or cooling systems including heat pumps and other heating and cooling loops, in, for example, the automotive industry.
