摘　　要：为解决2,6-二氨基-3,5-二硝基吡啶-1-氧化物(ANPyO)难以用常规方法精制的难题,以铜盐、二甲基亚砜、硫酸和水为原料,通过ANPyO铜配合物的合成及解络合过程除去杂质2,6-二氨基-3,5-二硝基吡啶(ANPy),得到精制的ANPyO,通过对固、液废弃物的再利用,获得了精制ANPyO的新方法。用红外、核磁、元素分析、扫描电镜、差示扫描量热等对中间体及产物进行了表征。结果表明,通过该方法精制ANPyO的收率大于89%,纯度大于99%,有机溶剂需求量少。To solve the difficulty of refining 2,6-diamino-3,5-dinitropyridine-1-oxide(ANPyO)by conventional method,the impurity 2,6-diamino-3,5-dinitropyridine(ANPy)was removed and refined ANPyO was obtaned via synthesis of ANPyO copper complexes and decomplexation process using copper salts,DMSO,H_2SO_4 and water as starting materials.Through the reuse of solid-liquid waste,a new method for purification of ANPyO was obtained.The intermediates and products were characterized by IR,NMR,elemental analysis,SEM and DSC.The results show that the yield of ANPyO refined by this method is greater than 89%,the purify is more than 99%,and the demand of organic solvent is less.
