摘要：
Process for preparing isophoronediamine, characterized in thatA) isophoronenitrile is subjected directly in one stage to aminating hydrogenation to give isophoronediamine in the presence of ammonia, hydrogen, a hydrogenation catalyst and possibly further additions, and in the presence or absence of organic solvents; orB) isophoronenitrile is first converted fully or partly in at least two or more than two stages to isophoronenitrile imine, and this isophoronenitrile imine is subjected to aminating hydrogenation to give isophoronediamine as a pure substance or in a mixture with other components and/or isophoronenitrile, in the presence of at least ammonia, hydrogen and a catalyst.
