wherein one or more components (L) having a boiling point below the boiling point of the alkyl halide silane (S1) are at least partially removed from the reaction mixture, partial mixture or individual reactant components by distillation before or during the reaction of components (S1) and (S2).
本发明涉及一种从烷基卤代硅烷(S1)和不饱和有机羧酸盐(S2)出发,制备通式(1)的硅烷(S)的方法;通式(1)为(R1)2C═C(R1)C(O)O—(R2)—Si(R3)z(OR4)3-z;通式(2)为X-(R2)-Si(R3)z(OR4)3-z;通式(3)为Mw+[(R1′)2C═C(R1)C(O)O−]w;其中R1、R1′、R2、R3、R4、X、Mw+、w和z的含义如权利要求书所述,其特征在于,在组分(S1)和(S2)反应之前或反应过程中,从反应混合物、部分混合物或单个反应物组分中,至少部分地通过蒸馏去除沸点低于烷基卤代硅烷(S1)的沸点的一种或多种组分(L)。
