ABSTRACT:
The cataytic hydrogenation of an olefinically unsaturated dinitrile reactant of the formula ##EQU1## wherein each R is an alkylene or an alkylidene radical, and each R' is an alkyl radical, is carried out in the presence of NH.sub.3, hydrogen, water, a tertiary alkanol, and a catalyst comprising a first component selected from the group consisting of elemental palladium, palladium compounds which are reducible by hydrogen to elemental palladium, and mixtures thereof, and a second component selected from the group consisting of elemental ruthenium, ruthenium compounds which are reducible by hydrogen to elemental ruthenium, and mixtures thereof.
