ABSTRACT:
A process is disclosed for the hydrogenolysis of a saturated acyclic starting material of the formula C.sub.n H.sub.a X.sub.b F.sub.c (X is Cl and/or Br, n is 1 to 4, a 0 to 3, b is 1 to 4, and c is 1 to 9) which involves reacting the starting material with hydrogen at an elevated temperature of about 300.degree. C. or less in the presence of a catalyst containing a catalytically effective amount of palladium supported on trivalent chromium oxide and in the presence of an acid of the formula HZ (Z is Cl, Br, and/or F) to produce a product compound of the formula C.sub.n H.sub.d X.sub.e F.sub.f where e is less than b and d+e equals a+b.
