Example 3 was repeated except that 29.7 g of 2-(2-cyanoethyl)-cyclohexanone (purity 96%, 0.189 mole) and 1,200 ml of liquid ammonia (720 g, 42.4 moles) were passed upwardly through the first reactor, per hour, at a pressure of 250 bar and a temperature of 70° C. Hydrogen was then added to the stream at a rate of 125 standard liters (5.6 moles) per hour, and the effluent from the in-line imination reactor was passed upwardly through the hydrogenation reactor at a pressure of 250 bar and a temperature of 125° C. After an on-stream time of 17.8 hours the separation and distillation measures as per Example 2 had yielded, besides 66.4 g of decahydroquinoline, 365 g of 2-(3-aminopropyl)-cyclohexylamine. The yield of 2-(3-aminopropyl)-cyclohexylamine was 69.7% of theory.
