Versuchsvorschrift

Cyclohexanone (50 g) and ethylene diamine (60 g) were mixed in ethanol (50 ml) at room temperature and allowed to stand for one hour. Meanwhile Adams catalyst (1 g) in ethanol (20 ml) was pre-reduced on a Parr apparatus at 60 p.s.i. under hydrogen for one hour. The imine solution was added to the hydrogenation flask and reduced at 60 p.s.i. for 18 hours. The catalyst was removed by filtration and the ethanol removed under vacuum. N-Cyclohexyl ethylene diamine was obtained on distillation of the crude product collecting the fraction boiling between 110°-120° C. at 20 ram.
