3-Aminomethyl-3,5,5-trimethylcyclohexylamine (i.e., isophoronediamine, abbreviated as IPDA) is used as a starting material for preparing substances such as 3-isocyanatomethylene-3,5,5-trimethylcyclohexyl isocyanate (i.e., isophorone diisocyanate, abbreviated as IPDI) or polyamides, and also used as a curing agent for epoxy resins. 3-Aminomethyl-3,5,5-trimethylcyclohexylamine is prepared, on an industrial scale, by reacting 3-cyano-3,5,5-trimethylcyclohexanone (i.e., isophoronenitrile, abbreviated as IPN) with ammonia to form 3-cyano-3,5,5-trimethylcyclohexylamine (i.e., isophoronenitrilimine, abbreviated as IPNI), followed by a reductive amination reaction of IPNI with hydrogen in the presence of ammonia in a catalytic way. The above reaction processes are as follows:
