摘　　要：本文以含0.1 mol/L盐酸的氯化镁饱和溶液为加成试剂,进行了环氧基测定的探讨,并考察了反应时间、反应温度对分析准确度的影响。实验结果标明,在反应温度60℃条件下,反应45 min后,分析相对误差降至1%以内;与离子色谱测定方法比较,其测定结果吻合,可用于工业化生产中环氧琥珀酸(盐)的测定。Used saturated solution of magnesium chloride containing 0.1 mol/L hydrochloric acid as the addition reaction reagent,the determination of epoxy group was investigated in this paper.These factors of reaction time and reaction temperature on the analysis accuracy were also explored.The results indicated that：the relative error of the determination maintained at 60 ℃ temperature for 45min was below 1%,the results conformed with the ion chromatographic（IC）method.This method to epoxy determination was convenient for the determination of epoxysuccinic acid（salt）in industrial production.
