摘　　要：介绍了一条对苯二甲醚的合成新方法,该方法利用化学平衡移动的原理,在反应的同时将产物移出反应体系,使得反应更为充分,不但提高了反应收率,而且大幅度降低了辅助原材料硫酸二甲酯的用量,同时因产物是与水蒸汽一同馏出,所得产品纯度极高,不需精制及可得到高纯度产品。A new method of synthesizing 1,4 -dimethoxybenzene was introduced. According to mobile chemical balance principle, when the product was conveyed out of the reaction system, the reaction carried more fully, which can not only increase the yield of reaction, but also significantly reduce the amount of supporting raw materials dimethyl sulfate. Due to water vapor together with the distillate, so the high purity of the product was obtained.
