Versuchsvorschrift

Then, 7.5 g of LiAlH4 was added to 250 ml of diethyl ether, followed by stirring for a little while. Then, a solution of 56 g of the above ester in 50 ml of diethyl ether was added dropwise in 2 hours at below 5° C. After the addition, the mixture was stirred at room temperature for 2 hours and allowed to stand for 15 hours. After the reaction, 30 ml of 5% hydrochloric acid was added, and 6N-hydrochloric acid was added to provide a pH of about 1, followed by extraction with ether. The product was washed with water, dried and subjected to removal of the solvent by distillation, followed by vacuum distillation to obtain 39.5 g of 2-octyloxypropanol as a fraction of 107° C./3 mmHg.
