Abstract: 1,1'-Bis-(3-aminopropyl)-2,2'-diimidazole of the formula I, and a novel process for the preparation of 1,1'-bis-(3-aminopropyl)-2,2'-diimidazole of the formula I, in which 2,2'-diimidazole of the formula II, is reacted with acrylonitrile of the formula III, in the presence of basic catalysts at temperatures from 80 to 150 DEG C, and the product is hydrogenated with an excess of hydrogen on cobalt-, nickel-, ruthenium- and/or noble-metal-containing catalysts in the presence of ammonia, at temperatures from 40 to 200 DEG C and under pressures from 10 to 200 bar.
