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 (2-dichloro-1,1,1,2-tetrafluoroethane, CCl2FCF3), HCFC-124 (2-chloro-1,1,1,2-tetrafluoroethane, CF3CHFCl), HCFC-143a (1,1,1-trifluoroethane, CF3CH3), CFO-1113 (2-chloro-1,1,2-trifluoroethene, CClF═CF2), HFO-1123 (1,1,2-trifluoroethene, CHF═CF2), HFO-1132a (1,1-difluoroethene, CH2═CF2), TFE (tetrafluoroethene, CF2═CF2), HCFO-1122 (2-chloro-1,1-difluoroethene, CHCl═CF2), 3,4,4,4-tetrafluoro-2-butanone (CH3C(═O)CHFCF3), acetyl fluoride (CH3C(═O)F), 2-chloro-2,3,3,3-tetrafluoropropanol (CF3CClFCH2OH), 2-chloro-2,3,3,3-tetrafluoropropyl acetate (CF3CClFCH2OC(═O)CH3), Zinc (2-chloro-2,3,3,3-tetrafluoropropoxy) chloride (CF3CClFCH2OZnCl2-chloro-2,3,3,3-tetrafluoropropoxy methyl acetate (CF3CFClCH2OCH2OC(═O)CH3), 1,3-bistrifluoromethyl-1,3-difluorocyclobutane (C6H4F8), 2,3,3,3-tetrafluoropropyl acetate (CF3CHFCH2OC(═O)CH3), dimethylformamide (DMF, HCON(CH3)2), pyridine (C5H5N), ethyl acetate, (CHClFCF3), acetic acid (CH3C(═O)OH), diethyl ether (CH3CH2OCH2CH3), acetic anhydride (CH3C(═O)OC(═O)CH3), methyl acetate (CH3C(═O)OCH3), dimethylacetamide (CH3C(═O)N(CH3)2), methanol (CH3OH), ethanol CH3CH2OH), methyl formate (HC(═O)OCH3), 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. |
