If there are 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, 190 g (0.56 mol) of 3,12-dihexyl-1,2-diazacyclododecane (diastereoisomeric mixture) and correspondingly reduced amounts of catalyst and solvent, with otherwise the same procedure, there is obtained as main fraction 130 g (68% of theory) of 7,16-diaminodocosane as colourless oil [b.p. 184° C./0.02-0.005 Torr; nD20 =1.4624; IR (liquid) inter alia bands at 3355, 3278 and 1613 cm-1 ].
