Abstract
A chlorine-donating perhalogenated hydrocarbon such as fluorocarbon 133a is reacted in the vapor phase with a hydrogen-donating halogenated hydrocarbon such as fluorocarbon 113a in the presence of a catalyst to produce a first halogenated fluorocarbon product with one less chlorine and one more hydrogen than the chlorine donating perhalogenated hydrocarbon and one less hydrogen and one more chlorine than the hydrogen donating halogenated hydrocarbon. Preferred catalysts are activated carbon and especially chromium oxides and oxyfluorides. The products such as fluorocarbon 123 are useful in aerosol, refrigerant and foaming applications, and as intermediates to other chlorofluorocarbons.
