摘要
研究了原料配比、缩合反应时间、缩合反应温度等因素对产品收率的影响,得到的优化反应条件为:溴苯与镁粉的物质的量比为1:1.1,二苯基二氯硅烷的用量为溴苯的0.8倍,缩合反应时间为3h,缩合反应温度为45～50℃,三苯基硅醇收率稳定在74.57%以上,质量分数大于98%,并用红外光谱对产品进行了验证。
The effects of the ratio of reactants , condensation reaction time, condensation reaction temperature on the product yield had been investigated. The optimum synthesis conditions were determined that the condensation reaction took place at 45℃- 50℃ for three hours with the male ration of bromobenzene and magnesium powder = 1 ： 1. 1, of bromobenzene and dichlorodiphenylsilane = 1：0.8, the yield of triphenylsilanol was above 74.57% , and mass fraction of triphenylsilanol in the product was above 98%. The structure of product was confirmed by IR.
