ABSTRACT:
The reductive amination of 1,3,3-trimethyl-5-oxocyclohexane carbonitrile (IPN) with ammonia and hydrogen in the presence of nickel- or cobalt Raney catalysts to 3-aminomethyl-3, 5,5-trimethyl-cyclohexyl amine is achieved in a single stage with a good yield and requires no pressure distillation if a co-catalyst selected from the group consisting of salts of nickel, cobalt, yttrium, lanthanum and cerium is used in an amount of 0.01 to 0.5 mole per mole Raney catalyst.
