methodnfor the preparation of 3-aminomethyl-3,5,5-trimethylcyclohexylaminenby reacting 3-cyano-3,5,5-trimethylcyclohexanone with 3-aminomethyl-3,5,5-trimethylcyclohexylaminenand then ornsimultaneous addition of ammonia under a hydrogen pressurenfrom 50 to 300 bar in the presence of a hydrogenation catalyst at hydrogenation temperaturesnfrom 50 to 150 ° C,ncharacterized in thatnthe reaction is carried out without separation of the water of reaction, 3-cyano-3,5,5-trimethylcyclohexanonenwith 3-aminomethyl-3,5,5-trimethylcyclohexylamine in a molar ratio ofn0.5: 1 to 5: 1, ammonia and 3-cyano-3,5,5-trimethylcyclohexanonenin weight rationfrom 0.1: 1 to 10: 1 and hydrogenation catalysts, at leastnone of the elements selectednfrom the group of copper or an element of the VIII. subgroupnof the Periodic Table of the Elements. |
