摘　　要：在乙醇和二甲苯联用体系里,通过双酚A与氯乙醇反应,后期直接加碱结晶,制备了羟乙基化双酚A。确定了制备羟乙基化双酚A的最佳工艺条件:1 mol的双酚A溶解在500 g乙醇中,与氯乙醇的比例为1.0∶2.5,反应温度控制在85～90℃。The hydroxyethyl bisphenol A was prepared via the reaction of bisphenol A with chlorethanol and late direct alkali crystallization in coupled system of ethanol and dimethylbenzene. The best technological conditions of reparation for hydroxyethyl bisphenol A were determined, the ratio of 1 tool bisphenol A dissolved in ethanol of 500 g and the chlorethanol is 1.0 ： 2.5, the reaction temperature must be held down between 85 ℃ and 90 ℃.
