摘　　要：本文采用了氯乙酸法合成DTPA,讨论了不同的反应工艺条件对DTPA产率的影响。总结出了较好的洗涤方法。并得出了最佳的反应条件:反应温度为60℃,反应物料比n氯乙酸∶nNa OH∶n二乙烯三胺∶nNa OH=5∶5.25∶1.2∶5.25,反应时间8h,酸化p H值为1.67。通过本次实验我们得到的DTPA的最高产率为91.04%。This paper adopted the method of chloroacetic acid to synthesize divinyl three amine five acetic acid,the different reaction conditions on divinyl three amine five acetic acid production rate were discussed. The better washing methods were summarized. The best process parameters were ：the reaction temperature was 60℃,reaction material ratio nchloroacetic acid∶nNa OH∶n∶divinyl three amine∶nNa OH= 5∶5. 25∶1.2∶5∶25,about 8 h reaction time,acidic p H=1.67 or so. Through the experiments most prolific rate of divinyl three amine five is about 91.04%.
