Abstract

Process for the preparation of organic polyamines by hydrolytic decomposition of non-distillable polyisocyanates or distillation residues, as obtained in the distillative production of organic polyisocyanates, characterized in that the non-distillable polyisocyanates or the distillation residues, if necessary after the a pre-treatment with ammonia under transformation of the isocyanate groups present in urea groups, are reacted under pressure at a temperature of 100-300ºC with aqueous solutions of primary and secondary amines, ammonia or ammonia-dissociating compounds under the reaction conditions .
