以三甲基氯硅烷、水和氢氧化钠为原料水解合成六甲基二硅氧烷(MM)。实验结果表明,氢氧化钠的加入有利于提升反应收率,提高产品纯度,降低反应要求,以及简化反应后处理过程。MM的收率最高可达到99.95%,产品纯度可达到99.876%。 Hexamethyldisiloxane (MM) was hydrolyzed by using trimethylchlorosilane, water and sodium hydroxide as raw materials. The experimental results show that the addition of sodium hydroxide helps to improve the reaction yield, improve product purity, reduce the reaction requirements, and simplify the post-reaction process. MM yield up to 99.95%, product purity up to 99.876%.
