ABSTRACT:
This invention provides an improved process for the manufacture of 1,1,1,2-tetrafluoroethane by the reaction of HF and trichloroethylene in the presence of a catalyst to form a mixture comprising 2-chloro-1,1,1-trifluoroethane and 1,1,1,2-tetrafluoroethane and, optionally, other organic by-products. The improvement resides in conducting the reaction in a single reaction zone while recovering the 1,1,1,2-tetrafluoroethane from the mixture and recycling the 2-chloro-1,1,1-trifluoroethane and, optionally, other organic by-products from the mixture to the reaction along with trichloroethylene and HF.
