Versuchsvorschrift

The commercially available glycidol (0.17 mol, 11 ml) was added dropwise to stirred ethanolamine (1 eq, 1.4 mol, 84.3 ml) at 0° C. Once addition was complete the reaction was allowed to warm up to room temperature, while stirring overnight. The product was then distilled (Ethanolamine first distilled at 60° C. at 1 Torr, and the desired product at 170° C. at 1 Torr). The product was obtained a clear oil that cooled to a clear viscous syrup (0.122 mol, yield=72%).
