Abstract: 3-Aminomethyl-3,5,5-trimethyl-cyclohexylamine (IPDA) with a cis:trans isomer ratio of at least 70/30 is obtained by catalytic imination of 3-cyano-3,5,5-trimethyl-cyclohexanone (IPN) followed by catalytic hydrogenation of the resulting imine in presence of an acid. A process for the production of IPDA with a cis:trans isomer ratio of at least 70/30 comprises: (a) imination of IPN with ammonia in presence of an imination catalyst at 20-150 degrees C and 1.5-30 Mpa, and (b) hydrogenation of the resulting imine at 80-160 degrees C and 5-30 Mpa in presence of ammonia on catalysts containing copper and/or a Group VIII metal and also in presence of an acid in amounts corresponding to an acid number of 0.1-2 based on the IPN used.

Abstract: Prepn. of 3-aminomethyl-3,5,5-trimethylcyclohexylamine (isophorone diamine; IPDA) from 3-cyano-3,5,5-trimethyl-cyclohexanone (isophorone nitrile; IPN) is carried out in three separate reaction zones by: (a) reacting IPN with excess liquid NH3 at 20-150 deg.C and 50-300 bar; (b) hydrogenating the reaction prod. with H2 in the presence of excess NH3 at 50-100 deg.C and 50-300 bar; and (c) hydrogenating the reaction prod. with N2 at 110-160 deg.C and 150-300 bar. Acidic metal oxide catalyst is used in stage (a); and hydrogenation catalyst, opt. with basic components or on neutral or basic supports, in stages (b) and (c).
