<p>Compositions comprising CF3CCIFCH2OH, CF3CCIFCH2OZnCI, and CF3CCIFCH2OC(=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, CCI2FCF3), HCFC-124 (2-chloro- 1,1,1,2-tetrafluoroethane, CF3CHFCI), HFC-143a (1,1,1 -thfluoroethane, CF3CH3), CFO-1113 (2-chloro-1,1,2-trifluoroethene, CCIF=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, CHCI=CF2), 3,4,4,4-tetrafluoro-2-butanone (CH3C(=O)CHFCF3), acetyl fluoride (CH3C(=O)F), 2-chloro-2,3,3,3- tetrafluoropropanol (CF3CCIFCH2OH), 2-chloro-2,3,3,3-tetrafluoropropyl acetate (CF3CCIFCH2OC(=O)CH3), Zinc (2-chloro-2,3,3,3- tetrafluoropropoxy) chloride (CF3CCIFCH2OZnCI2-chloro-2,3,3,3- tetrafluoropropoxy methyl acetate (CF3CFCICH2OCH2OC(=O)CH3< /sub>), 1,3- bisthfluoromethyl-1,3-difluorocyclobutane (C6H4F8), 2,3,3,3- tetrafluoropropyl acetate (CF3CHFCH2OC(=O)CH3), dimethylformamide (DMF, HCON(CH3)2), pyridine (C5H5N), ethyl acetate, (CHCIFCF3), 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-methyl pyrrolidinone, dimethyl sulfoxide, acetonitrile, benzonithle, 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.</p> |
