ABSTRACT:
A method is disclosed for the selective preparation of 3-aminomethyl-3,5,5-trialkylcyclohexylamine by preparing dried 3-cyano-3,5,5-trialkylcyclohexylimine from the reaction of 3-cyano-3,5,5-trialkylcyclohexanone with ammonia in the presence of a drying agent in an amount at least sufficient to retain the water present or generated during the imine-forming reaction, and hydrogenating the dried 3-cyano-3,5,5-trialkylcyclohexylimine in the presence of a cobalt-containing catalyst at elevated temperature and pressure.
