Heterogeneous hydrogenolysis of some fluorocarbons

Journal Article · · J. Catal.; (United States)
The catalytic C-F hydrogenolysis of six fluorocarbons including CH/sub 2/=CHF, CH/sub 3/CH/sub 2/F, CHF=CHF, CH/sub 2/=CF/sub 2/, CH/sub 3/CHF/sub 2/, and CH/sub 3/CF/sub 3/ has been studied. C-F hydrogenolysis took place more readily for compounds with no more than one F atom attached to each carbon and much less readily for compounds with two or more F atoms attached to the same carbon. The apparent activation energy values range from 12 kcal mol/sup -1/ for CH/sub 3/CH/sub 2/F to 26 kcal mol/sup -1/ for CH/sub 3/CHF/sub 2/ and CH/sub 3/CF/sub 3/. Possible mechanisms for the C-F hydrogenolysis were also discussed.
