Versuchsvorschrift

After the cooling process, the high pressure vessel is charged, by a trickle-bed procedure and under a hydrogen pressure of 270 bar, with 0.4 liters/hour of adipodinitrile, 1.2 liters/hour of liquid ammonia and 4.5 liters/hour of crude hydrogenation mixture, the temperature in this procedure being kept at 140° C. Analysis of the crude hexamethylenediamine by gas chromatography after the ammonia has been evaporated from the hydrogenation mixture gives 99.69% by weight of hexamethylenediamine, 0.06% by weight of 1,2-diaminocyclohexane and 0.12% by weight of 2-aminocyclopentylamine.
