A tertiary aminoalcohol having a tert-amino group(s) in the main chain and hydroxyl groups at the terminals. The use of this compound for purposes different from that of ordinary amines and amine derivatives is expected. A process for producing the tertiary aminoalcohol wherein a catalyst comprising copper, a transition metal element of the fourth period and a platinum group element of the group VIII, and further optionally containing an alkali metal or an alkaline earth metal is used. A process for producing polyurethane using the above-mentioned tertiary aminoalcohol which can solve the problems occurring in the production of a polyurethane using a tertiary amine which has a strong irritating odor and is highly irritant to the skin as a catalyst, for example, deteriorations of working atmosphere and sales appeal of the polyurethane. The chemical structure of the above-described tertiary aminoalcohol is as follows: ##STR1##

A process for producing an N-alkyl-N-methylamine or an N-alkenyl-N-methylamine in a high yield from a higher alcohol and methylamine comprising the step of reacting a higher alcohol with methylamine in the presence of a catalyst comprising copper and a fourth period transition metal of the Periodic Table, except for chromium, or a catalyst comprising copper, a fourth period transition metal of the Periodic Table, except for chromium, and an element of the platinum group VIII of the Periodic Table, at a pressure ranging from atmospheric pressure to 100 atm. G., at a reaction temperature ranging from 100.degree. to 250.degree. C., with hydrogen gas being introduced into the reaction system while water produced in the reaction is removed from the reaction system and the amount of methylamine in the gaseous mixture which contains no matter formed through the reaction and is exhausted from the reaction system is regulated from 5 to 50% by volume.
