  • Process for the Production of Dichlorotrifluoroethane
    Publication number: 20090259079
    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 the increase in temperature across the or each reactor from the inlet side to the outlet side is controlled. The dichlorotrifluoroethane may be purified and then used as it is or used to prepare pentafluoroethane.
