If there is used in the manner described under (a), instead of 942 g (3.79 mols), of 3,12-dipropyl-1,2-diaza-1,5,9-cyclododecatriene, 208 g (0.75 mol) of 3,12-dibutyl-1,2-diaza-1,5,9-cyclododecatriene (diastereoisomeric mixture) and correspondingly reduced amounts of catalyst and solvent, the procedure otherwise being the same, there is obtained as the main fraction 132.8 g (62.3% of theory) of 5,14-diaminooctadecane as colourless oil (b.p. 149° C./0.001 Torr; nD20 =1.4593; IR (liquid) inter alia bands at 3333, 3267 and 1613 cm-1).
