Versuchsvorschrift

Under nitrogen stream, 30 g of sodium ethoxide was added to 851.8 g (18.5 mol) of ethanol, and the mixture was heated to 80° C. Then, 500 g (1.85 mol) of tetradecyl glycidyl ether were added dropwise thereto. The mixture was stirred for 18 hours at the same temperature. Thereafter, ethanol was distilled off, and 10.8 g of 85% phosphoric acid was added thereto, followed by washing the resultant mixture with water three times. After water washing, distillation was performed under reduced pressure, to thereby obtain 446 g of 1-tetradecyl-3-ethylglycerol (yield 76.2%).
