ABSTRACT:
An improved process for the vapor phase fluorination, especially fluorination of 1,1,1-trifluoro-2-chloroethane (CFC-133a) with HF to produce 1,1,1,2-tetrafluoroethane (HFC-134a) employs a catalyst which preferably consists essentially of boehmite and Cr(OH)Cl.sub.2.2H.sub.2 O, combined and extruded to form particulates and then heated in nitrogen.
