摘要: 目前二苯乙烯苯酚聚氧乙烯醚的合成工艺温度高,合成产品色泽深。为解决这一问题,本文介绍了苯乙烯和苯酚在催化剂H催化下生成二苯乙烯苯酚,以二苯乙烯苯酚和环氧乙烷为原料,三氟化硼乙醚络合物为催化剂制备二苯乙烯苯酚聚氧乙烯醚(10)。研究分析了催化剂、反应温度、反应时间等因素对产品性能的影响,结果表明:二苯乙烯苯酚的优选合成工艺为n(苯乙烯)∶n(苯酚)=2.05∶1,催化剂H用量(按苯酚质量计)为1.75%,反应温度100℃,反应时间4.5h。二苯乙烯苯酚聚氧乙烯醚的优选合成工艺为反应温度110~115℃,反应压力0.035MPa,催化剂用量(按物料总质量计)为0.02%。最终制备的聚醚产品色泽浅,分子量分布窄,目标组分二苯乙烯苯酚聚氧乙烯醚(10)的含量超过50%。

Abstract: The main problems with current synthetic process of diphenylethene phenol polyoxyethylene ether were high temperatures and deep colors. To solve this problem,a new process was proposed that phenethylene reacted with phenol at the present of catalyst H and formed diphenylethene phenol,and diphenylethene phenol reacted with ethylene oxide at the present of boron trifluoride ether complex and formed diphenylethene phenol polyoxyethylene ether. The effects of catalyst,reaction temperature,reaction time,and other factors on the performance of diphenylethene phenol polyoxyethylene ether were discussed. The optimal process conditions of diphenylethene phenol were that the mole ratio n(phenethylene):n(phenol)=2.05:1,reaction temperature 100℃,reaction time 4.5h,dosage of catalyst H 1.75% based on mass of phenol. And the optimal process conditions of diphenylethene phenol polyoxyethylene ether were that reaction temperature 110-115℃,reaction pressure 0.035MPa,dosage of boron trifluoride ether complex 0.020% based on mass of material. Ultimately,the polyether had the characteristics of low color,narrow distribution of molecular weight,and the content of diphenylethene phenol polyoxyethylene ether(10) was over 50%.
