A LIQUID PHASE PROCESS FOR PREPARING ALIPHATIC TERTIARY AMINE WHICH COMPRISES THE STEPS OF FORMING A MIXTURE OF ALCOHOL AND AMINE, SAID ALCOHOL BEING SELECTED FROM THE GROUP CONSISTING OF SATURATED AND ETHYLENICALLY UNSATURATED, SUBSTITUTED AND UNSUBSTITUTED, STRAIGHT AND BRANCHED CHAIN ALIPHATIC ALCOHOLS HAVING A PRIMARY HYDROXY GROUP, SAID AMINE BEING SELECTED FROM THE GROUP CONSISTING OF SATURATED AND ETHYLENTICALLY UNSATURATED, SUBSTITUTED AND UNSUBSTITUTED, STRAIGHT AND BRANCHED CHAIN, ALIPHATIC AMINES HAVING AT LEAST ONE REACTIVE HYDROGEN ATTACHED TOITS NITROGEN ATOM, SAID MIXTURE HAVING EXCESS ALCOHOL EQUIVALENT PER SAID REACTIVE HYDROGEN, SAID ALCOHOL AND SAID AMINE CONTAINING HYDROXY AND AMINO GROUPS AS THE ONLY REACTIVE GROUPS, AND SUBSEQUENTLY REACTING SAID MIXTURE IN THE PRESENCE OF A CATALYTIC AMOUNT OF HYDROGENATION-DEHYDROGENATION CATALYST AT A REACTION TEMPERATURE OF FROM 90*C. TO 230*C., THEREBY PRODUCING ALIPHATIC TERTIARY AMINE AND BY-PRODUCT WATER, AND CONTINUOUSLY REMOVING BY-PRODUCT WATER SIMULTANEOUSLY WITH THE PRODUCTION OF SAID ALIPHATIC TERTIARY AMINE.
