This invention relates to a process for producing 1,1,1,2-tetrafluoroethane (HFC-134a). The process reacts, 1,1,1-trifluoro-2- chloroethane (HCFC-133a) and hydrogen fluoride in a first reactor. The product resulting from the first reaction step is brought to a second reactor together with trichloroethylene and hydrogen fluoride. The second reaction is conducted at a higher temperature than the first reactor. Optionally, HC1 is removed prior to removal of the crude HFC- 134a product. Unreacted HCFC-133a, trichloroethylene and hydrogen fluoride may be recycled back to the first reactor.

Procédé de production de 1,1,1,2-tétrafluoroéthane (HFC-134a), qui consiste à faire réagir du 1,1,1-trifluoro-2-chloroéthane (HCFC-133a) et du fluorure d'hydrogène dans un premier réacteur. Le produit résultant de la première réaction est introduit dans un second réacteur avec du trichloréthylène et du fluorure d'hydrogène. La seconde réaction est conduite à une température plus élevée que la première réaction. Eventuellement, du HCl est enlevé avant le prélèvement du produit HFC-134a brut. Le HCFC-133a, le trichloréthylène et le fluorure d'hydrogène qui ne sont pas entrés en réaction peuvent être recyclés et renvoyés dans le premier réacteur.
