Vorschrift

A 300-ml flask equipped with a stirrer, reflux tube and dropping funnel was charged with 40.5 g (0.66 mol) of ethanolamine and 8.6 g of ethanol. While heating and stirring the mixture at 80° C., an ethanol solution of 4.08 g (11.8 mmol) of 2-hydroxyoctadecyl glycidyl ether was added dropwise over 3 hours. After the resultant mixture was heated and stirred further for 3 hours, it was poured into 500 ml of ice water to collect crystals formed by filtration. The thus-obtained crystals were recrystallized again from n-hexane, thereby obtaining 3.58 g (yield: 75%) of the title compound (Ia-12).
