2087728 9202477 PCTABS00010 Gas phase and liquid phase processes are disclosed which use interconversion of CF3CHFCl and CF2HCF2Cl in contact with catalyst consisting essentially of halided aluminum oxide and/or aluminum halide at elevated temperatures to increase the mole ratio of one of said compounds in a composition relative to the other. Also disclosed is use of said interconversion along with hydrogenolysis in processes for producing mixtures of CF3CH2F and CF2HCF2H from certain compositions comprising CF2HCF2Cl such that the mole ratio of CF3CH2F to CF2HCF2H in the product mixtures produced from said compositions may be increased or decreased.
