There are provided processes for the preparation of γ-methacryloxypropylsilane compounds which comprise carrying out the reaction of allyl methacrylate with a hydrosilane compound in the presence of a platinum catalyst, while allowing at least one of a hindered phenol compound and an aromatic amine compound to coexist in the reaction system with an alkylamine compound or an amide compound, or with a gas containing molecular oxygen, or with a phenol compound having an aminoalkylene group. By using these processes as provided, gelation of the reaction mixture in the reaction system and during the course of purification thereof by distillation can effectively be avoided, and the desired γ-methacryloxypropylsilane compounds can be obtained in good yield.
本发明提供了制备γ-甲基丙烯酰氧基丙基硅烷化合物的工艺,包括在铂催化剂存在下进行甲基丙烯酸烯丙酯与氢硅烷化合物的反应,同时允许受阻酚化合物和芳香胺化合物中的至少一种与烷基胺化合物或酰胺化合物,或与含分子氧的气体,或与具有氨基烷基的酚化合物共存于反应体系中。通过使用所提供的这些工艺,可以有效地避免反应混合物在反应体系中和通过蒸馏提纯过程中的凝胶化,并能以良好的收率获得所需的γ-甲基丙烯酰氧基硅烷化合物。
