ABSTRACT:
A process is disclosed for producing HCFC-124 and HFC-125 which includes reacting certain pentahaloethane starting materials (e.g., CF.sub.3 CHCl.sub.2) in the gaseous phase at an elevated temperature in the presence of certain supported metal catalysts containing effective amounts of zinc. A catalyst of metal fluoride on a fluorinated alumina support having an atomic ratio of F to Al of at least 2.7:1 and containing .beta.-aluminmum fluoride, is employed.
