PROCESS FOR THE PREPARATION OF 1,1,1,3,3-PENTAFLUOROPROPANE |
摘要 |
This invention is related to the preparation of hydrofluorocarbons (HFCs). Specifically, it relates to the manufacture of 1,1,1,3,3-pentafluoropropane, CF3CH2CF2H (HFC-245fa) by the steps comprising (1) the formation of CCl3CH2CCl3 by the reaction of CCl4 with vinylidene chloride; (2) the conversion of CCl3CH2CCl3 to CF3CH2CF2Cl by reaction with HF in the presence of a fluorination catalyst, selected from TiCl4, SnCl4 or mixtures thereof; and (3) reduction of CF3CH2CF2Cl to CF3CH2CF2H.
