The experimental result showed that three byproducts was formed and the optimal condition was as follows: the molar ratio of ethylene glycol, hydrogen bromide, and acetic acid was 1:1:1.3, when ethylene glycol was 1 mol, refluxed 5 h under the action of 100 mL toluene.

结果表明：较适宜的合成条件为乙二醇1 mol， n：n：n=1：1：1.3，在带水剂甲苯(100 mL)的作用下，回流反应5 h，约4 h后分两次追加0.12×2 mol醋酸酐，合成效果最好，产率可达到95%，反应副产2-溴乙醇及少量的1， 2-二溴乙烷、乙二醇二乙酸酯和二乙二醇二乙酸酯。
