HCID 3018623Tris(2-(2-ethoxyethoxy)ethyl)amine収率 68%

実験手順

51.6 g (i.e., 0.215 mol) of tris-(2-chloroethyl)-amine hydrochloride were added to the above mixture (a). The mixture was subsequently heated at the reflux temperature of the 2-ethoxyethanol for 12 hours and the solvent was then distilled under reduced pressure. The excess sodium 2-ethoxyethanolate was neutralized by adding 12 cm3 of aqueous HCl (10 N) thereto. The sodium chloride was filtered off and the solution was distilled. The tris-(3,6-dioxaoctyl)-amine distilled between 200° C. and 210° C. under a pressure of 1 mm Hg. The yield was 68%.
