A process for preparing an acryloyloxysilane, comprising: reacting a metal salt of a carboxylic acid having the formula [CR22=CR1CO-]aMa+ (I), with a haloorganoalkoxysilane having the formula XR3Si(OR4)nR53-n (II) at a temperature of from 50 to 160 °C and in the presence of a catalyst, and in the presence of water, an alcohol comprising 1 to 5 carbon atoms, or a combination of water and an alcohol comprising 1 to 5 carbon atoms, to form a mixture comprising an acryloyloxysilane and a metal halide having the formula Ma+X-a (III), wherein R1 is H, R7COO- Ma+, or C1-C6 hydrocarbyl, each R2 is independently R1 or [COO-]Ma+, Ma+ is an alkali metal cation or alkaline earth metal cation, a is 1 or 2, X is halo, R3 is C1-C6 hydrocarbylene, each R4 is independently C1-C10 hydrocarbyl, each R5 is independently R1 and n is an integer from 1 to 3.
一种制备丙烯酰氧基硅烷的方法,包括:在催化剂存在下,以及存在水、1至5个碳原子的醇或水和1至5个碳原子的醇的组合物的情况下,将具有公式[CR22=CR1CO-]aMa+(I)的羧酸金属盐与具有公式XR3Si(OR4)nR53-n(II)的卤代有机烷氧基硅烷在50至160℃的温度下反应,以形成包含丙烯酰氧基硅烷和具有公式Ma+X-a(III)的金属卤化物的混合物,其中R1为H、R7COO-Ma+或C1-C6烃基,每个R2独立地为R1或[COO-]Ma+,Ma+为碱金属离子或碱土金属离子,a为1或2,X为卤素,R3为C1-C6烃基亚ethylene,每个R4独立地为C1-C10烃基,每个R5独立地为R1,n为1至3的整数。
