The present invention relates to 3-aminomethyl-1-cyclohexylamine and to a process for preparation thereof by a) reacting cyclohexenone with hydrogen cyanide in the presence of a basic catalyst, b) reacting the cyclohexanonenitrile obtained in stage a) with ammonia in the presence of an imine formation catalyst, and c) reacting the 3-cyanocyclohexylimine-containing reaction mixture obtained in stage b) with hydrogen and ammonia over hydrogenation catalysts.
The present invention further relates to the use of 3-aminomethyl-1-cyclohexylamine as a hardener for epoxy resins, as an intermediate in the preparation of diisocyanates, as a starter in the preparation of polyetherols and/or as a monomer for polyamide preparation.
