HCID 2628351-(Chloromethyl)-1,1,3,3,3-pentamethyldisiloxane

実験手順

134 ml. dimethylchloromethylchlorosilane (1 mole) and 127 ml. (1 mole) of trimethylchlorosilane are mixed and shaken thoroughly. When 600 ml. of distilled water is added, exothermic hydrolytic reactions occur immediately. The mixture is shaken on a mechanical shaker overnight to complete hydrolysis. The upper oily layer is separated and is dried over anhydrous sodium carbonate. After drying, the product is distilled through a column of 13 theoretical plates and the fraction which distills at 151°-152° C. is collected. The yield of pentamethylchloromethyldisiloxane (b.p. 151.8° C., d25 = 0.910, nD20 = 1.4106) is 30%.
