Abstract

1,191,610. Hydrogenation catalysts. FARBENFABRIKEN BAYER A.G. 20 Nov., 1968 [4 Dec., 1967], No. 55032/68. Heading B1E. [Also in Division C2] A catalyst for use in the hydrogenation of halogenated aromatic nitro compounds to the corresponding amines comprises Raney nickel and 0.1 - 20% (by weight based on the Raney nickel) of a thiocyanate of formula M(SCN) x in which x is 1 or 2 or M represents an alkali metal or an alkaline earth metal, H or NH 4 , a saturated or unsaturated C 1 -C 18 aliphatic hydrocarbon radical, an aromatic radical optionally substituted by a C 1 -C 10 alkyl radical or an araliphatic radical with up to 12 carbon atoms.
