실험 절차

A 300-ml flask equipped with a stirrer and a dropping funnel was charged with 45.8 g (0.75 mol) of ethanolamine and 9 g of ethanol. While stirring the mixture at 80° C., 13.4 g (50 mmol) of 1,2-epoxyoctadecane were added dropwise over 2 hours. Water was added to the resultant reaction mixture, and white crystals formed were collected by filtration, washed with water and then recrystallized from methanol, thereby obtaining 12.3 g (yield: 74.6%) of the title compound (IIc-1).
