Abstract
A process for preparing fluorine-rich organic compounds containing one or two carbon atoms from organic fluoro compounds of lower fluorine content in which starting partially or completely halogenated fluoro carbon compounds having at least one halogen atom other than fluorine, e.g., CHCl.sub.2 F, CHClF.sub.2, CCl.sub.2 F.sub.2, CCl.sub.3 F, C.sub.2 Cl.sub.3 F.sub.3, C.sub.2 Cl.sub.2 F.sub.4 and C.sub.2 Cl.sub.4 F.sub.2, are contacted under disproportionation conditions with a catalyst system of a specific type which comprises 0.1 - 5% by weight, as metal, of a nickel(II) halide, titanium(III) chloride or titanium(III) fluoride and a balance of an aluminum compound such as activated alumina, silica, alumina or aluminum fluoride.
