Abstract: A process for the production of dichlorotrifluoroethane is described. The process comprises reacting perchloroethylene with hydrogen fluoride (HF) at elevated temperature in the vapour phase in at least one reactor in the presence of a fluorination catalyst. The process is operated so that 30 weight % or more of the perchloroethylene reactant that is fed to the at least one reactor remains unreacted having passed through the or each reactor. The dichlorotrifluoroethane may be purified and then used as it is or used to prepare pentafiuoroethane.

Abstract: A process for the production of dichlorotrifluoroethane is described. The process comprises reacting perchloroethylene with hydrogen fluoride in the vapour phase at elevated temperature in at least one reactor in the presence of a fluorination catalyst to produce a composition comprising dichlorotrifluoroethane, hydrogen chloride, unreacted perchloroethylene and unreacted hydrogen fluoride. The composition that is produced is subjected to a separation step to recover a first fraction comprising dichlorotrifluoroethane and a second fraction comprising perchloroethylene and hydrogen fluoride. The second fraction is further separated into a hydrogen fluoride-rich fraction and a perchloroemylene-containing, organic-rich fraction which are then recycled. The dichlorotrifluoroethane that is recovered may be used to prepare pentafluoroethane.

Abstract: A process for the production of pentafluoroethane is described. The process comprises reacting perchloroethylene with hydrogen fluoride in the vapour phase in a first reactor or a first plurality of reactors in the presence of a fluorination catalyst to produce a composition comprising dichlorotrifluoroethane, hydrogen chloride, unreacted hydrogen fluoride and perchloroethylene. This composition is subjected to a separation step to yield a purified composition comprising at least 95 weight % of dichlorotrifluoroethane and less than 0.5 weight % of compounds having the formula C 2 C 16-X F X , where x is an integer of from 0 to 6, based on the total weight of organic compounds in the composition. The composition from the separation step is then reacted with hydrogen fluoride in the vapour phase in a second reactor or a second plurality of reactors in the presence of a fluorination catalyst to produce a composition comprising pentafluoroethane and less than 0.5 weight % of chloropentafluoroethane, based on the total weight of organic compounds in the composition.
