In the autoclave described in Example 1 there were placed 20 g of 5-formylvaleronitrile and 3 g of Pd (2%) on Al2O3 powder and 0.41 g of lithium hydroxide under protective gas (argon). The autoclave was then sealed and 140 ml of NH3 were forced in. The mixture was stirred using a magnetic stirrer and was heated to 100° C. and the overall pressure raised to 80 bar by forcing in hydrogen and then kept at this value by continuous replenishment with hydrogen. After a period of 23 hours the autoclave was depressurized and the hydrogenation effluent analyzed by gas chromatography. The products formed comprised 59.01% of 6-aminocapronitrile and 5.1% of hexamethylene diamine (conversion 100%).
