摘要：
Compositions comprising CF3CClFCH2OH, CF3CClFCH2OZnCl, and CF3CClFCH2OC(═O)CH3 are useful in processes to make HFO-1234yf. Compositions comprising HFO-1234yf may comprise at least one additional compound selected from the group consisting of CFC-114a, HCFC-124, HFC-143a, CFO-1113, HFO-1123, HFO-1132a, tetrafluoroethene, HCFO-1122, 3,4,4,4-tetrafluoro-2-butanone, acetyl fluoride, 2-chloro-2,3,3,3-tetrafluoropropanol, 2-chloro-2,3,3,3-tetrafluoropropyl acetate, Zinc (2-chloro-2,3,3,3-tetrafluoropropoxy)chloride, 2-chloro-2,3,3,3-tetrafluoropropoxy methyl acetate, 1,3-bistrifluoromethyl-1,3-difluorocyclobutane, 2,3,3,3-tetrafluoropropyl acetate, dimethylformamide, pyridine, ethyl acetate, acetic acid, diethyl ether, acetic anhydride, methyl acetate, dimethylacetamide, methanol, ethanol, methyl formate, pyrazine, pyrimidine, N-methylpyrrolidine, N-methylpiperidine, hexamethylphosphoramide, tetrahydrofuran, 1,4-dioxane, N-methylpyrrolidinone, dimethyl sulfoxide, acetonitrile, benzonitrile, and mixtures thereof. Compositions comprising HFO-1234yf are useful, among other uses, as heat transfer compositions for use in refrigeration, air-conditioning and heat pump systems.
