Siloxy-substituted silane-containing polymerizable silicones are prepared in high purity by metering a substituted alkoxysilane into a mixture of disiloxane, acetic acid, and acid catalyst, adding acetyl chloride, separating an acidic phase from a product phase, and adding hexamethyldisilazane to the product phase, which is then distilled.
通过将取代烷氧基硅烷计量加入二硅氧烷、乙酸和酸催化剂的混合物中,加入乙酰氯,分离出酸性相和产物相,并向产物相中加入六甲基二硅氮烷,然后进行蒸馏,可以制备高纯度的含有硅烷聚合物的硅氧烷。
