Abstract: PRODUCTION OF DIAMINODICYCLOHEXYLALKANES OR ETHERS BY HYDROGENATION OF DIAMINODIPHENYLALKANES OR ETHERS AT ELEVATED TEMPERATURE AND SUPERATOMSPHERIC PRESSURE IN THE PRESENCE OF A SUPPORTED CATALYST CONTAINING COBALT OR NICKEL WHICH HAS BEEN PREPARED BY TREATING THE CARRIER MATERIAL (AND/OR THE FINISHED CATALYST) WITH A BASIC REACTING ALKALI METAL OR ALKALINE EARTH METAL COMPOUND AND THEN WITH A BINDER, APPLYING FINELY DIVIDED COBALT OXIDE OR NICKEL OXIDE OR FINELY DIVIDED COMPOUNDS OF COBALT OR NICKEL WHICH CHANGE INTO THE OXIDES WHEN HEATED, AND THEN DRYING AND HEATING IT TO 500* TO 1100*C.

Abstract: AN IMPROVED PROCESS FOR THE PRODUCTION OF N-SUBSTITUTED MORPHOLINES BY HEATING A N-SUBSTITUTED BIS-(B-HYDROXYETHYL)-AMINE OR BIS-(B-HYDROXYPROPYL)-AMINE IN THE PRESENCE OF A WATER-ELIMINATING CATALYST, THE IMPROVEMENT CONSISTING IN CARRYING OUT THE REACTION AT A TEMPERATURE OF FROM 180* TO 270* C. IN THE PRESENCE OF WATER OR IN THE PRESENCE OF A HIGH-BOILING ORGANIC SOLVENT WHICH IS INERT UNDER THE REACTION CONDITIONS.

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.

Abstract: A PROCESS FOR THE CONTINUOUS PRODUCTION OF DIAMINODICYCLOHEXYLALKANES BY CONTACTING DIAMINODIPHENYLALKANES WITH HYDROGEN AT ELEVATED TEMPERATURE AND SUPERATMOS-PHERIC PRESS PHERIC PRESSURE IN THE PRESENCE OF HYDROGENATION CATALYSTS CONTAINING COBALT, WHEREIN THE IMPROVEMENT CONSISTS IN CARRYING OUT THE REACTION AT A TEMPERATURE OF MORE THAN 180*C. AND A PRESSURE OF MORE THAN 50 ATMOSPHERES IN THE PRESENCE OF A HYDROGENATION CATALYST CONTAINING COBALT WHOSE COPPER CONTENT IS LESS THAN 0.5% BY WEIGHT WITH REFERENCE TO COBALT AND MAINTAINING A WATER CONTENT OF LESS THAN 0.4% BY WEIGHT IN THE REACTION MIXTURE. DIAMINODICYCLOHEXYLALKANES ARE SUITABLE AS HARDENERS FOR EPOXY RESINS AND FOR THE PRODUCTION OF POLYAMIDES.
