Zusammenfassung:	A PROCESS FOR COPRODUCTION OF 6-AMINOCAPRONITRILE AND HEXAMETHYLENEDIAMINE STARTING FROM A MIXTURE COMPRISING A PHOSPHORUS-CONTAINING COMPOUND AND ESSENTIALLY ADIPONITRILE AND OBTAINED BY REACTION OF BUTADIENE WITH HYDROCYANIC ACID IN THE PRESENCE OF A CATALYST COMPRISING A PHOSPHORUS-CONTAINING COMPOUND COMPRISES (1)REDUCING THE WEIGHT PROPORTION OF PHOSPHORUS-CONTAINING COMPOUND, CALCULATED AS PHOSPHORUS, IN THE MIXTURE, (2)PARTIALLY HYDROGENATING THE RESULTING MIXTURE IN THE PRESENCE OF A CATALYST TO FORM AN (ALPHA),( )-AMINONITRILE, AND (3)REMOVING 6-AMINOCAPRONITRILE AND HEXAMETHYLENEDIAMINE FROM THE MIXTURE.
