３−アミノメチル−３，５，５−トリメチルシクロヘキシルアミンの製造法

摘要

The invention relates to an improved process for preparing 3-aminomethyl-3,5,5-trimethylcyclohexylamine, referred to hereinafter as isophoronediamine or IPDA for short, by means of catalytic hydrogenation and/or catalytic reductive amination (also referred to as aminating hydrogenation) of 3-cyano-3,5,5-trimethylcyclohexanone, also called isophoronenitrile or IPN for short hereinafter.
