Abstract
A novel morpholino-substituted tertiary amine compound is proposed which is tris[2-(4-morpholino)ethyl] amine or a derivative thereof by optionally substituting methyl and/or ethyl groups for a part or all of the hydrogen atoms at the 2- and 6-positions of the morpholine rings. The amine compound can be synthesized by heating tris[N,N-di(2-hydroxyethyl)aminoethyl] amine or a corresponding derivative thereof in a mixture with sulfuric acid. The amine compound is useful as a catalyst for the urethane-forming reaction between a polyisocyanate compound and a polyol compound without the problems of environmental pollution or unpleasant odor as in the use of methyl or ethyl morpholine for the same purpose.
