2′-dioxide were nitrated in 100% HNO3 at −10 °C to give 4,4′-dinitramino-[3,3′-bi(1,2,5-oxadiazole)]-5,5′-dioxide (3) and 4,4′-diamino-[3,3′-bi(1,2,5-oxadiazole)]-2,2′-dioxide (4). Nine nitrogen-rich salts were prepared and were characterized by infrared and multinuclear NMR spectroscopy, elemental analysis, differential scanning calorimetry (DSC) and X-ray single crystal diffraction in some cases. Their
4,4'-二氨基-[3,3'-二(1,2,5-恶二唑)]-5,5'-二氧化物和4,4'-二氨基-[3,3'-二(1,2 ,5-5-恶二唑)]-2,2'-二氧化物在-10°C下于100%HNO 3中硝化,得到4,4'-二氨基氨基-[3,3'-bi(1,2,5-恶二唑) ] -5,5'-二氧化物(3)和4,4'-二氨基-[3,3'-二(1,2,5-恶二唑)]-2,2'-二氧化物(4)。制备了九种富氮盐,并在某些情况下通过红外和多核NMR光谱,元素分析,差示扫描量热法(DSC)和X射线单晶衍射进行了表征。使用测得的密度和计算出的地层热,通过EXPLO 5代码评估了它们的爆炸特性。灵敏度通过标准BAM方法确定。一些新分子表现出与HMX竞争或超过HMX的爆炸和其他特性。
