ABSTRACT:
The catalytic hydrogenation of an unsaturated dinitrile reactant of the formula ##STR1## wherein each R is an alkylene or an alkylidene radical, and each R' is an alkyl radical, is carried out in the presence of a secondary amine formation suppressant, hydrogen, a suitable diluent, and a catalyst composed of a catalytic component supported on high purity alumina, the catalytic component being selected from ruthenium, rhodium, palladium, cobalt and nickel in element form or in the form of a compound which is reducible by hydrogen to the elemental metal.
