    摘要: AN IMPROVED PROCESS FOR THE PRODUCTION OF 1,2-DIAMINES BY REACTION OF 1,2-EPOXIDES WITH AMMONIA, PRIMARY AMINES OR SECONDARY AMINES IN THE PRESENCE OF WATER, HYDROGEN AND HYDROGENATION CATALYSTS AT ELEVATED TEMPERATURE AND SUPERATMOSPHERIC PRESSURE WHEREIN THE IMPROVEMENT COMPRISES USING A SUPPORTED HYDROGENATION CATALYST HAVING A LARGE INTERNAL SURFACE AREA. THE PRODUCTS ARE SUITABLE AS COMPLEX-FORMING SUBSTANCES FOR HEAVY METAL IONS.

    摘要: 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.

    摘要: 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.
