摘要
以 PW_(12)/USY-1固载杂多酸为催化剂,苯酚和丙酮为原料,催化缩合双酚A。通过对催化剂制备的正交试验,优选了催化剂的制备条件:H_3PW_(12)O_(40)与USY-1质量比为1:1,H_3PW_(12)O_(40)浓度为25％,480℃焙烧4 h制备的催化剂活性最高。通过对缩合反应的正交试验,优化了双酚A合成反应条件:苯酚与丙酮摩尔比为8:1,催化剂用量为反应物总质量的9％,反应温度为120℃,反应时间为3 h,其产率可达62.6％。
The synthesis of bisphenol A from phenol and acetone was catalyzed by solid heteropolyacid PW12/USY-1 and the optimum preparational conditions of catalyst were studied. It was found that catalyst activity of USY-1 was the highest under weight ratio of H3PW12O40/USY-l = l:1 ,the concen-tration of H3PW12O40 of 25%,the temperature of 480 ℃ and the time of 4 h. Factors influencing on the yield of bisphenol A reaction were studied by using orthogonal design. The yield of the bisphenol A reached up to 62. 6% under molar ratio of phenol/acetone = 8 : 1 ,the solid heteropolyacid catalyst of 9%,the reaction temperature of 120 ℃and reaction time of 3 h.
