ABSTRACT:
A process is disclosed for producing HCFC-133a which includes reacting certain trihaloethene starting materials (e.g., trichloroethene) with HF 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.-aluminum fluoride, is employed.
