Versuchsvorschrift

44.0 g (1.1 mol) of NaOH pellets were added to 360 g (3.0 mol) of diethyleneglycol monomethyl ether, and 176 g (1.0 mol) of 2-(2-methoxyethoxy)ethyl glycidyl ether was gradually dropwise added while stirring at 70° C. After the completion of dropwise addition, the mixture was stirred for about one hour and then stood for cooling at room temperature. Then, the mixture was neutralized with hydrochloric acid, a precipitated salt was filtered off and the liquid was condensed. The liquid was purified by vacuum distillation to give 222 g of 1,3-bis[2-(2-methoxyethoxy)ethoxy]-2-propanol (yield: 75%). The distillation temperature was from 171 to 175° C./0.8 mmHg.
