Abstract: Preparation of isophoronediamine (3-aminomethyl-3,5,5-trimethylcyclohexylamine) by aminating hydrogenation of isophorone nitrile and/or isophorone nitrile-imine in presence of ammonia and hydrogen over a shaped Raney catalyst, the new feature is that the catalyst is in the form of hollow particles.

Abstract: Procedimiento para la preparación de isoforona-diamina a partir del isoforona-nitrilo, de la isoforona-nitrilo-imina o de mezclas que contienen isoforona-nitrilo e isoforona-nitrilo-imina, mediante hidrogenación aminante en presencia de por lo menos amoníaco e hidrógeno, utilizándose un catalizador de Raney moldeado a base de cobalto, caracterizado porque el catalizador de Raney se presenta en la forma de cuerpos huecos.
