Versuchsvorschrift

108.8 grams of 2-hydroxyoctyl amine were dissolved in 500 ml of toluene, heated to reflux, treated within 10 minutes under stirring with 18.5 grams of glycidol and held at reflux for 2 hours. Subsequently, the solvent was drawn off and the excess amine distilled off in a vacuum. There were obtained as a residue 49.5 grams (90.5% of theory) of N-(2,3-dihydroxypropyl)-N-(2-hydroxyoctyl) amine which after recrystallization from ethylacetate gave colorless crystals having a melting point of 85°-90° C.
