ABSTRACT:
A haloethane is dechlorinated by reacting in the gaseous phase a haloethane selected from CCl.sub.2 FFCClF.sub.2, CClF.sub.2 CClF.sub.2 and CCl.sub.2 FCCl.sub.2 F with ethylene in the presence of a transition metal catalyst selected from iron, nickel, vanadium and chromium oxides, chlorides and fluorides and recovering a perhaloethylene and vinyl chloride. Perhaloethylenes are used as monomers for halogenated polymers. Vinyl chloride is also a widely used monomer.
