compound 6,6′-(diazene-1,2-diyl)bis(4,5,7-trinitrobenzo[c][1,2,5]oxadiazole 1-oxide) (DADBTNBO) is introduced where its computational assessments show that it is a thermally stable explosive with high detonation performance. Herein, the DADBTNBO explosive with high yield and purity is synthesized in 2 steps. The synthesis mechanisms of these steps were investigated. The products of these steps are
介绍了一种新型有机含能化合物 6,6′-(二氮烯-1,2-二基)双(4,5,7-三硝基苯并[c][1,2,5]恶二唑 1-氧化物)(DADBTNBO),其计算评估表明,它是一种具有高爆轰性能的热稳定炸药。在此,分两步合成了高产率和高纯度的DADBTNBO炸药。研究了这些步骤的合成机制。使用红外光谱、核磁共振和元素分析来鉴定这些步骤的产物。1 HNMR、13 CNMR和元素分析结果证实了DADBTNBO的高纯度。使用 X 射线衍射、扫描电子显微镜和透射电子显微镜分析确定了 DADBTNBO 炸药的特性。然后,通过可靠的预测方法计算了DADBTNBO的重要特性,包括爆热、爆压和速度、绝热指数、炸药的格尼速度、比冲和冲击灵敏度。预测结果表明,与耐热烈性炸药六硝基芪(HNS)相比,在DADBTNBO中引入呋喃基团可以提供更高的密度、爆轰和燃烧性能。DADBTNBO的预测爆速、爆压、爆热和比冲分别为8
