Abstract
The design and synthesis of insensitive energetic materials are a necessary and challenging work. The synthesis of novel nitrogen-rich salts based on 5-(5-Nitro-1H-1,2,4-triazol-3-yl)-1H-tetrazole (H2NTT) has been presented. Structural characterization of these two salts was accomplished by utilizing NMR, MS, IR spectroscopy, and X-ray diffraction. The standard heats of formation were calculated, and the differential scanning calorimetry (DSC) and sensitivity test were carried out. Their detonation performances were estimated by EXPLO 5 program. These newly synthesized salts showed highly positive heat of formation and low sensitivity. It is noteworthy that the diaminoguanidine salt b exhibited good detonation performance superior to traditional explosive TNT (Trinitrotoluene), making it a prospective candidate for insensitive energetic material.
设计和合成不敏感的高能材料是一项必要而具有挑战性的工作。本文介绍了基于 5-(5-硝基-1H-1,2,4-三唑-3-基)-1H-四氮唑（H2NTT）的新型富氮盐的合成。利用核磁共振、质谱、红外光谱和 X 射线衍射对这两种盐进行了结构表征。计算了标准形成热，并进行了差示扫描量热法（DSC）和灵敏度测试。用 EXPLO 5 程序估算了它们的引爆性能。这些新合成的盐类显示出较高的正形成热和较低的灵敏度。值得注意的是，二氨基胍盐 b 表现出了优于传统炸药 TNT（三硝基甲苯）的良好起爆性能，因此有望成为不敏感的高能材料。
