ABSTRACT:
As replacements for chlorofluorcarbons, hydro(chloro)fluorocarbons are synthesized by hydrogenating chlorofluorocarbons over a Pd/ZnO/.gamma.--Al.sub.2 O3 catalyst. The ZnO is partially reduced before use and assists the Pd to function catalytically for days instead of hours despite the evolution of halogen.
