A PROCESS FOR THE PRODUCTION OF DIAMINOALKANES WHICH COMPRISES PASSING AT LEAST ONE COMPOUND SELECTED FROM THE GROUP CONSISTING OF ALKANEDIOLS OF 2 TO 12 CARBON ATOMS, ALKANOLAMINES OF 2 TO 8 CARBON ATOMS, ALKYLENE OXIDES OF 2 TO 6 CARBON ATOMS AND ALKYLENIMINES OF 2 TO 6 CARBON ATOMS, AND A MEMBER SELECTED FROM THE GROUP CONSISTING OF AMMONIA AND AN ALKYLAMINE OF 1 TO 8 CARBON ATOMS, IN THE PRESENCE OF HYDROGEN AT A TEMPERATURE OF FROM 150* TO 300*C. AND AT A PRESSURE OF AT LEAST 10 ATMOSPHERES OVER A CATALYST WHICH CONTAINS AT LEAST ONE METAL SELECTED FROM THE GROUP CONSISTING OF COBALT AND NICKEL, WHICH CATALYST IS OBTAINED FROM THE OXYGEN COMPOUNDS OF THE SAID METALS BY SINTERING AT A TEMPERATURE OF FROM 700*C. UP TO A TEMPERATURE 20*C. BELOW THE MELTING POINT OF THE METAL COMPOUNDS AND THEN REDUCING THE SINTERED METAL COMPOUND BY TREATMENT WITH HYDROGEN.
