摘　　要：探讨了邻苯二甲酸二乙酯(DEP)作为邻苯二甲酸二丁酯(DBP)内标物在测量DBP含量中的表现。通过实验设计、数据测量以及分析论证,验证了DEP作为内标物的准确性与稳定性。DEP作为DBP的内标物能够准确测量DBP的含量,其标准偏差为0.00233602,变异系数为0.56524%。用该方法测试绿色低碳丁烷法顺酐生产中的后气提塔釜贫溶剂的DBP含量,结果仍表现为良好的线性关系,邻苯二甲酸二乙酯和后气提塔釜贫溶剂混合稳定,为DBP含量的准确测定提供了可靠的方法。The performance of diethyl phthalate(DEP)as an internal standard for measuring dibutyl phthalate(DBP)content was studied.Through rigorous experimental design,precise data measurement,and in-depth analysis and demonstration,the accuracy and stability of DEP as an internal standard have been fully verified.DEP as an internal standard for DBP,can accurately measure the content of DBP with a standard deviation of 0.00233602 and a coefficient of variation of 0.56524%.This method was used to test the DBP content of the lean solvent in the post stripping kettle of green low-carbon butane method for the production of maleic anhydride.The results stil showed a good linear relationship,and the mixture of diethyl phthalate and the lean solvent in the post stripping kettle was stable,providing a reliable method for accurate determination of DBP content.
