IN A PROCESS FOR PRODUCING TRI-ALKYL TERTIARY AMINES HAVING FROM 8 THROUGH 22 CARBON ATOMS IN EACH ALKYL GROUP WHEREIN SAID TERTIARY AMINES ARE DERIVED FROM A NITROGEN-CONTAINING MATERIAL SELECTED FROM THE GROUP CONSISTING OF ALIPHATIC NITRILES, PRIMARY ALIPHATIC AND SECONDARY ALIPHATIC AMINES, AND MIXTURES THEREOF, THE IMPROVEMENT WHICH COMPRISES THE STEPS OF FORMING A MIXTURE OF SAID NITROGEN-CONTAINING MATERIAL AND A CATALYTIC AMOUNT OF FROM ABOUT 0.05% TO 5% BY WEIGHT OF NON-PYROPHORIC, FINELY DIVIDED, REDUCED AND STABILIZED FROM OF NICKEL SUPPORTED ON KIESELGUHR; HEATING THIS MIXTURE AT A TEMPERATURE OF FROM ABOUT 400* TO ABOUT 450*F. WHILE SPARGING THE MIXTURE WITH HYDROGEN; MAINTAINING THE HEATED MIXTURE UNDER A PRESSURE OF FROM ABOUT 0 TO ABOUT 100 P.S.I.; AND REMOVING AMMONIA AS SAID TERTIARY AMINE IS FORMED UNTIL THE REACTION IS SUBSTANTIALLY COMPLETED.
