The process for the preparation of 1,1,1,3,3-pentafluoropropane, in which 1,1,1,3,3-pentafluoropropane is reacted with a fluoride in the presence of a hydrofluorocarbon catalyst. Preferred 1,1,1,3,3-pentachloropropane is 1,1,1,3,3-pentachloropropane by reaction of vinyl chloride with carbon tetrachloride. |
