A process of preparing tris-(ether-amines) of the formula: N--[A--O--(B--O).sub.n --R].sub.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).sub.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.
一种制备三(醚胺)的过程,其
化学式为:N--[A--O--(B--O).sub.n --R].sub.3,其中R代表一个碳氢基团,A和B代表脂肪二基基团,n为0到4之间的整数,通过在存在占
乙二醇单醚的10到40重量百分比的氢化-脱氢催化剂的情况下,通过对
乙二醇单醚的
氨解反应来实现。所生产的三(醚胺)包括三(3,6-二氧杂辛基)胺、三(3,6,9-三氧杂十一基)胺、
三(3,6-二氧杂庚基)胺和三(3,6-二氧杂癸基)胺。
