Zusammenfassung:The invention concerns a method for preparing tris(ether-amines) of formula (I): N[A-O-(B-O)n-R]3 wherein R, A, B and n are as defined in Claim 1, comprising the reaction, in liquid phase, of an alkylene-glycol monoether of formula (II): HO-A-O-(B-O)nR wherein R, A, B and n are as defined in Claim 1, with an ammonolysis agent selected among ammonia and an etheramine of formula (I'): H3-pN[A-O-(B-O)nR]p wherein: A, B, n and R are as defined in Claim 1 and p represent 1 or 2, at a temperature ranging between 100 and 250° C., by contacting reagents with a hydrogenation-dehydrogenation catalyst.
