ABSTRACT:
A novel catalyst is prepared by codepositing hexavalent chromium oxide and a transition metal compound, preferably titanium trichloride, on alumina, followed by fluorinating the resulting combination. The catalyst is useful in the fluorination of a haloethylene of the formula CX.sub.2 .dbd.CHX (where the X's are chlorine or bromine or a combination of the two) in the vapor phase to form 1,1,1,2-tetrafluoroethane.
