The new compound 4-amino-3-aminomethylpiperidine is manufactured by hydrogenating 4-amino-3-cyano-1,2,5,6-tetrahydropyridine in a manner which is in itself known. The 4-amino-3-cyano-1,2,5,6-tetrahydropyridine used as the starting substance can be obtained by cyclisation of bis-cyanoethylenated ammonia. The new compound 4-amino-3-aminomethylpiperidine represents a valuable curing agent for epoxide resins, and advantageously 0.5 to 1.3 equivalents of nitrogen-bonded active hydrogen atoms of the 4-amino-3-aminomethylpiperidine are used per 1 equivalent of epoxide groups of the polyepoxide compound. |
