To eliminate impurities (particularly 1-chloro-2,2-difluoroethylene) from raw 1,1,1,2-tetrafluoroethane (F134a), a gaseous mixture of raw F134a and hydrofluoric acid is treated, in gas phase and in the presence of a fluoridation catalyst, at a temperature of between 200 and 380 degrees C and a pressure of between atmospheric pressure and 2.5 MPa, the molar ratio HF/F134a being between 0.05 and 0.5.

Pour éliminer les impuretés (en particulier le 1-chloro-2,2-difluoroéthylène) présentes dans le 1,1,1,2-tétrafluoroéthane (F134a) brut, on traite en phase gazeuse, en présence d'un catalyseur de fluoration, un mélange gazeux de F134a brut et d'acide fluorhydrique à une température comprise entre 200 et 380°C et sous une pression comprise entre la pression atmosphérique et 2,5 MPa, le rapport molaire HF/F134a étant compris entre 0,05 et 0,5.
