Abstract

L'invention concerne l'industrie chimique. Elle a pour objet un procédé pour produire l'isomère symet/ou l'isomère asym du tétrafluoréthane, à savoir le 1,1,1,2-tétra-fluoroéthane et/ou le 1,1,2,2-tétrafluoro-éthane, par réaction avec de l'hydrogène à une température élevée en présence d'un catalyseur d'hydrogénation, d'un halogénoéthane comprenant quatre ou cinq atomes de fluor et en particulier de 1,1-dichloro-1,2,2,2-tétrafluoroéthane et/ou de 1,2-dichloro1,1,2,2-tétrafluoroéthane. Le procédé est préféré pour la préparation des isomères du tétrafluoroéthane de pureté élevée.
