Abstract:
A process for the catalytic hydrogenolysis of a cyclic or acyclic compound having the formula C.sub.n H.sub.m F.sub.p X.sub.q wherein n is an integer from 1 to 6, m is an integer from 0 to 12, p is an integer from 1 to 13, q is an integer from 1 to 13 and each X is independently selected from Cl and Br, provided that m+p+q equals 2n+2 when the compound is saturated and acyclic, equals 2n when the compound is saturated and cyclic or is olefinic and acyclic, and equals 2n-2 when the compound is olefinic and cyclic, using a catalyst of at least one metal selected from the group consisting of rhenium, cobalt, nickel, ruthenium, rhodium, palladium, osmium, iridium and platinum supported on carbon which is characterized by said catalyst containing less than about 200 ppm phosphorus and less than about 200 ppm sulfur.
