摘要
以四氯化硅、甲醇和环氧丙烷为原料，合成了硅卤协同阻燃增塑剂硅酸甲基三（氯丙基）酯。探讨了反应物质的量比、反应温度以及反应时间等对产率的影响，确定最佳的工艺条件为：n（四氯化硅）：n（甲醇）=1：1，n（四氯化硅）：n（环氧丙烷）-1：3．2，反应温度25℃，反应时间6h，收率98％。并采用FT-IR、^1HNMR、极限氧指数等技术表征硅酸甲基三（氯丙基）酯的分子结构。
A silicon-halogen synergistic flame retardant plasticizer methyl trichloropropyl silicate was synthesized by using silicon tetrachloride, methanol and propylene oxide as raw materials. The effect of reaction time, temperature and ratio of substances on the product yield was discussed. The optimal conditions for the preparation were found as follows： n（silicon tetrachloride） ： n（methanol）=1 ： 1; n （silicon tetrachloride） ： n（propylene oxide）=1 ： 3.2; reaction time 6 h at 25 ~C, with the product yield up to 98 %. The molecular structures of methyl trichloropropyl silicate and its related performance measurement were determined by means of FT-IR,^1H NMR and limited oxygen index （LOI） technique.
