1.由二乙三胺与一氯乙酸反应而得。将氯乙酸与氢氧化钠中和后，在低温下让氯化酸钠与二亚乙基三胺反应，生成的产物再经过净化处理最后得到产品DTPA。
2.二亚乙基三胺与氯乙酸缩合得二亚乙基三胺五乙酸。
3.将283.7kg一氯乙酸投入反应釜中，加220L蒸馏水搅拌溶解。于15℃滴加40%的NaOH 溶液，300kg，约1.5h加完。再在搅拌下滴加51.6kg二亚乙基三胺，滴加过程中把温度控制在２ ０℃左右。接着继续滴加120kgNaOH水溶液（40%） 。40℃反应10～12h。将反应液冷至5～10℃。搅拌下滴加260L浓盐酸，调ph值至1.6～1.7，放置过夜，滤出结晶，用400L冰水洗涤结晶，真空干
燥，得130kg左右的粗品。用蒸馏水脱色得纯品。反应式如下：
