摘要
以SiCl4、苯酚和环氧丙烷为原料,合成出新型硅卤协同阻燃增塑剂硅酸三(氯丙基)苯酯,研究了原材料配比、反应温度及反应时间等对硅酸三(氯丙基)苯酯产率的影响。结果表明,当SiCl4与苯酚的物质的量之比为1∶1,SiCl4与环氧丙烷的物质的量之比为1∶3.2,反应温度为50℃,反应时间为4 h时,硅酸三(氯丙基)苯酯的产率最高,为98%。
A new silicon-halogen synergistic flame retardant plasticizer trichloropropyl phenyl silicate was synthesized by using silicon tetrachloride, phenol and propylene oxide. The effect of reaction time, temperature and amount ratio of substance on product yield was discussed. Results showed that when n（ silicon tetrachloride）：n（phenol） was 1： 1, n（ silicon tetrachloride）：n（ propylene oxide） was 1： 3.2, reaction time was 4 h at 50℃ , the percentage of product yield was the highest, reached 98%.
