实验步骤: Using the apparatus employed in Examples 15-27, a mixture of 2-(2-ethoxyethoxy)ethanol (1 mole) and diethyl carbonate (3 mole) was passed through 11.5 grams of a magnesium:aluminum mixed metal oxide (3/16 inch pellets, Mg/Al 3:1) at a temperature of 225° C. and at a liquid feed rate of 0.29 milliliters/minute. After a period of one hour, a total of 30.2 grams of liquid was collected. Analysis was performed by capillary gas chromatography (FID) using a DB-1701 column. The results were (area %) as follows: a total of 30.2 grams of liquid was collected

实验步骤: The ether XXVI (213 g, 0.79 mole) at 25°C was stirred as 0.9 M lithium aluminum hydride in diethylene glycol diethyl ether (484 ml, 0.436 mole of Li Al H4) was added dropwise. Then the product was distilled at atmospheric pressure through a cold water condensor into an ice cooled receiver until 157 g of IV was collected. This distillate was fractionally distilled to give IV, b760 68.1°-68.2°C, of 99.7% purity (by gas-liquid chromatography) in 93% of the theoretical yield; density at 23°C was 1.554. The structure of IV was confirmed by proton NMR spectroscopy. was added dropwise Then the product was distilled at atmospheric pressure through a cold water condensor into an ice cooled receiver until 157 g of IV was collected This distillate was fractionally distilled
