A process of preparing tris-(ether-amines) of the formula: N-[A-O-(B-O)n-R]3 in which R represents a hydrocarbon radical, A and B represent alkanediyl radicals, and n is a whole number between zero and 4, by ammonolysis of an alkylene glycol mono-ether of the formula: HO-A-O-(B-O)n-R in the presence of 10 to 40 percent by weight of a hydrogenation-dehydrogenation catalyst, based on weight of said alkylene glycol monoether. The tris-(ether-amines) produced, such as tris-(3,6-dioxa-octyl)amine, tris-(3,6,9-trioxaundecyl)amine, tris-(3,6-dioxaheptyl)amine, and tris-(3,6-dioxadecyl)amine. |
