A method for preparing an organosilicon composition from an olefin and a silicon hydride with a hydrosilation catalyst PtL2X2, in an amount less than 1 ppm based on the weight of the product composition, is disclosed. The method is particularly useful in lowering the cost, coloration, and stability of the product, particularly when an oxirane-containing olefin is used in the hydrosilation. In this method no inhibitor is needed to prevent the undesired polymerization of oxiranes in the reaction, and no purification of the product is required after removal of volatile components, including solvent.
本发明公开了一种使用氢硅烷和烯烃以及含有氢硅化催化剂PtL2X2的方法制备有机硅组合物的方法,其中催化剂的用量小于1ppm,基于产品组合物的重量。该方法在降低产品成本、色彩和稳定性方面特别有用,特别是在使用含环氧基的烯烃进行氢硅化反应时。在该方法中,不需要使用抑制剂来防止反应中环氧烷的非预期聚合,并且在去除挥发性成分(包括溶剂)后不需要对产品进行纯化。
