1. Process for the preparation of tris-(8-hydroxy-3,6-dioxaoctyl)-amine, characterised in that an alkali metal is reacted with diethylene glycol in a molar ratio alkali metal/diethylene glycol of between 1/3 and 1/20, in that the alkali metal 5-hydroxy-3-oxapentanolate formed is condensed, in solution in diethylene glycol, with a tris-(halogenoethyl)-amine chosen from amongst tris-(2-chloroethyl)-amine hydrochloride, tris-(2-chloroethyl)-amine or tris-(2-bromoethyl)-amine, in a molar ratio alkali metal 5-hydroxy-3-oxapentanolate/tris-(halogenoethyl)-amine of between 3 and 5, and in that the resulting tris-(8-hydroxy-3,6-dioxaoctyl)-amine is recovered. |
