Abstract: A PROCESS FOR THE CATALYTIC HYDROGENATION OF DIAMINODIPHENYL ALKANES OR ETHERS, WHICH MAY BE SUBSTITUTED IN THE NUCLEI OR ON NITROGEN, IN THE PRESENCE OF HYDROGENATION CATALYSTS, PARTICULARLY THOSE CONTAINING COBALT AND MANGANESE. HYDROGENATION IS CARRIED OUT IN THE ABSENCE OF ALKALINE EARTH METAL OXIDES AT TEMPERATURES OF 140 TO 300*C. AND PRESSURES OF 150 TO 700 ATMOSPHERES. CYCLIC ETHERS HAVING AN OXYGEN ATOM IN THE RING, OR CYCLOHEXYLAMINE WHICH MAY BE SUBSTITUTED ON THE NITROGEN ATOM ARE USED AS SOLVENTS. THE SOLVENT CONCENTRATION IS 30 TO 90% BY WEIGHT BASED ON THE TOTAL OF SOLVENT AND COMPOUND TO BE HYDROGENATED. DIAMINODICYCLOHEXYL ALKANES OR ETHERS ARE SUITABLE FOR THE PRODUCTION OF HIGH POLYMERS.
