Abstract
The invention relates to a novel catalyst and process for producing various chlorofluorocarbons, hydrochlorofluorocarbons and hydrofluorocarbons said catalyst prepared by co-extruding aluminum/chromium oxide and optionally impregnating the aluminum/chromium oxide support with a metal salt. The chlorofluorocarbons, hydrochlorofluorocarbons and hydrofluorocarbons, i.e., e.g., 1,1-dichloro-2,2,2-trifluoroethane, produced using the catalyst of the invention are useful in a variety of industrial applications including blowing agent, refrigerant, sterilant gas and solvent applications.
