摘　　要：以四氯化硅、苯甲醇和环氧氯丙烷为原料,合成一种硅卤协同阻燃增塑剂硅酸苄基三(二氯丙基)酯。探讨反应物质的量比,反应温度以及反应时间等对产品收率的影响,筛选出最适宜的工艺条件为四氯化硅与苯甲醇的物质的量比为1∶1,四氯化硅与环氧氯丙烷的物质的量比为1∶3.3,反应温度为95℃,反应时间为8 h,产品产率为98%。并采用FTIR,1H-NMR,极限氧指数等表征了硅酸苄基三(二氯丙基)酯的分子结构及性能。Tsilicon-halogen synergistic flame retardant plasticizer benzyl tridichloropropyl silicate was synthesized by using silicon tetrachloride, benzyl alcohol and epoxy chloropropane as raw materials. The effect of reaction time, temperature and amount ratio of substance on the reaction yield was discussed. The optimal conditions for preparation were selected as follows： n （silicon tetrachloride）：n （benzyl alcohol） was 1：1; n （silicon tetrachloride）：n （epoxy chloropropane） was 1：3.3; reaction time was 8 h at 95 ℃ and the percentage of product yield could reach 98%. The molecular structures of benzyl tridiehloropropyl silicate and its related performance measurement were determined by means of FFIR, ^1HNMR and LOI technique.
