A process is disclosed for the conversion of halogenated methanes of the formula CClyH2-yF2 (wherein y is 1 or 2) to a mixture of conversion products. The process involves reacting certain halogenated hydrocarbon feeds and hydrogen (wherein said halogenated methanes are at least one mole percent of the halogenated hydrocarbon feed) in a reaction vessel of alumina, silicon carbide or at least one metal selected from gold, chromium, aluminum, molybdenum, titanium, nickel, iron, cobalt, and their alloys at a temperature of from about 500 DEG C. to 800 DEG C. and a pressure from abut 101 kPa to 7000 kPa to produce a mixture of conversion products of said halogenated methanes which comprises at least 5 mole percent C2H2F4, wherein the mole ratio of CH2FCF3 to CHF2CHF2 in said C2H2F4 is at least about 1:9. |
