一种乙二醇二乙酸酯的生产方法,涉及化工合成技术。在催化剂存在的条件下,以乙二醇甲醚和醋酸为原料,进行酯化反应,生产的乙二醇二乙酸酯粗品经过精馏后取得乙二醇二乙酸酯精品;催化剂为金属离子改性的具有复合增强型大孔的苯乙烯-二乙烯基苯磺酸型酸性阳离子交换树脂,所述离子交换树脂是以苯乙烯和二乙烯基苯单体聚合并在苯环上磺化制成的,离子为Zn2+、Fe3+、Al3+、Na+、Fe2+或K+中的任意一种。 A method for producing ethylene glycol diacetate relates to chemical synthesis technology. In the presence of a catalyst, ethylene glycol monomethyl ether and acetic acid as the raw material, the esterification reaction, the crude ethylene glycol diacetate produced after distillation obtained ethylene glycol diacetate boutique; the catalyst is a metal Ion-modified styrene-divinylbenzene sulfonic acid type acidic cation exchange resin having complex-enhanced macropores, the ion exchange resin being obtained by polymerizing styrene and divinylbenzene monomers and sulfonating on the benzene ring The ions are Zn2 +, Fe3 +, Al3 +, Na +, Fe2 + or K +.
