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, 100 g (0.24 mol) of crude 3,12-dinonyl-1,2-diaza-1,5,9-cyclododecatriene (diastereoisomeric mixture) and correspondingly reduced amounts of catalyst and solvent, with otherwise the same procedure, there is obtained, as the main fraction, 40.4 g (40% of theory) of 10.19-diaminooctacosane [m.p. 33°-37° C.; IR (CH2Cl2) inter alia bands at 3225 and 1582 cm-1 ].
