ABSTRACT:
1-Chloro-l,2,2-trifluoroethylene or 1,2,2-trifluoroethylene is prepared by reacting 1,1,2-trichloro-1,2,2-trifluoroethane and hydrogen in the presence of a catalyst which comprises at least one metal selected from the group consisting of palladium, rhodium and ruthenium and at least one metal selected from the group consisting of mercury, lead, cadmium, tin, indium, copper, bismuth, thallium and silver and a carrier selected from the group consisting of Al.sub.2 O.sub.3, SiO.sub.2 and activated carbon, whereby selectivities and yields of 1-chloro-1,2,2-trifluoroethylene or 1,2,2-trifluoroethylene are optimized by selecting the kinds of metals and supports.
