1,2-环己二醇二缩水甘油醚合成反应过程模拟

在三氟化硼-乙醚催化作用下,1,2-环己二醇(CHD)与环氧氯丙烷(ECH)发生醚化反应,加碱闭环脱去氯化氢得到1,2-环己二醇二缩水甘油醚。在对此合成反应过程分析的基础上,通过合理的假设,运用数学模型的方法对反应过程进行了模拟计算,建立了相应的数学模型。利用该模型可以从原料CHD,ECH和三氟化硼-乙醚的配比预测产物的环氧值。实验验证表明,该模型模拟计算得到的最高环氧值(0.607mol/100g)与实验值(0.595mol/100g)接近。

Process Simulation of Synthesizing Diglycidyl Ether of 1,2 -Cyclohexandiol

1,2-Cyclohexandiol reacted with epichlorohydrin using boron-trifluoride ethyl etherate as catalyst and then diglycidyl ether of 1,2-cyclohexandiol was obtained by cyclization and dehydrochlorination in presence of process reactions were simulated with mathematical method. A feasible mathematic model was established. In calculation with this model,epoxide value of diglycidyl ether of 1,2-cyclohexandiol could be predicted,which depended on mole ratio of 1,2-cyclohexandiol, epichlorohydrin and catalyst. Calculated result (0.607 mol/100 g) approached closely to the experimental (0.595 mol/100 g). This model could be applied to similar synthesis of other glycidyl ethers, which used boron trifluoride ethyl etherate as catalyst.
