一种双环化合物1,2-双（2,6-二氧-4-吗啉基）乙烷的合成方法
摘要：
本发明涉及一种带有酸酐结构的双环化合物1,2-双(2,6-二氧-4-吗啉基)乙烷的合成方法，它的合成路线为乙二胺四乙酸在惰性气体和脱水剂等条件下脱水，然后在乙酸酐中重结晶，并抽滤、干燥。在合成1,2-双(2,6-二氧-4-吗啉基)乙烷过程中，乙酸酐在反应过程中既是脱水剂，又是溶剂，后续处理简单方面可靠反应条件温和，产物纯度高。
摘要（英）：

The invention relates to a synthesis method of a bicyclic compound 1,2-bis(2,6-dioxo-4-morpholinyl)ethane with an anhydride structure. The synthesis method comprises a synthetic route: dehydrating ethylenediamine tetraacetic acid under conditions of an inert gas and a dehydrating agent and the like, then recrystallizing in acetic anhydride, carrying out suction filtration, and drying. In the process of synthesis of 1,2-bis(2,6-dioxo-4-morpholinyl)ethane, acetic anhydride is not only the dehydrating agent but also the solvent in the reaction process, subsequent processing is simple, convenient and reliable, reaction conditions are mild, and the product purity is high.
