摘要
用三氯氧磷、双酚A与苯酚反应制得化合物双酚-A双(磷酸二苯酯)(BDP)。采用单因素法分别对物料比、反应温度对产率的影响进行考察,确定了适宜的合成路线和反应条件。第一步,三氯氧磷和苯酚的物质的量之比为1:2.4,反应温度为110℃,反应时间为36h;第二步,中间体产物二苯基磷酰氯(DPCP)与双酚A的物质的量之比为2:1,反应温度为100℃,反应时间为19h,以MgCl2为催化剂(用量为苯酚总质量的1%)产品总收率为86.1%。
Bisphenol-A bis（diphenyl phosphate） was synthesized by phosphorus oxychloride bisphenol-A and phenol.The effect factors of process were studied respectively, including molar ratio and reaction temperature.The suitable synthesis conditions were studied.As follows： in the first step,the molar ratio of phosphorus oxychloride and phenol was 1：2.4,the reaction temperature was 110℃,the reaction time was 36 hours;in the second step,the molar ratio of intermediate compounds diphenyl chlorophosphat and bisphenol-A was 2：1,the reaction temperature was 100℃,the reaction time was 19 hours.Magnesium chloride was the catalyst and its dosage was 1% of the amount of all phenol.The final yield reached 86.1%.
