Abstract:
The present invention relates to a continuous process for the fluorination of perchloroethylene (PER) in the gas phase in a single stage with hydrofluoric acid (HF) in the presence of a catalyst to give, as major product, pentafluoroethane. The process is characterized in that it is carried out at a temperature of between 280 and 430° C. and with an HF/PER molar ratio of greater than or equal to 20.
