中文摘要:
      以4-氨基-2,6-二氯吡啶为原料,经过硝化和缩合两步反应,合成出一种新型耐热炸药,4-氨基-2,6-双(5-氨基-1H-四唑基)-3,5-二硝基吡啶(ABDP),总收率为36%。采用核磁共振、质谱及元素分析对产物结构进行表征。分别研究了3-氨基-1,2,4-三氮唑和5-氨基四唑与4-氨基-2,6-二氯-3,5-二硝基吡啶的缩合反应,结果发现,3-氨基-1,2,4-三氮唑中伯胺和仲胺的亲核性相近,5-氨基四唑中仲胺的亲核性优于伯胺。用热重(TG)和差示扫描量热法(DSC)研究了ABDP的热分解性能,发现其在322 ℃有一个热分解峰,322 ℃时总热失重量为97%,采用Rothstein方法计算4-氨基-2,6-双(5-氨基-2H-四唑基)-3,5-二硝基吡啶的爆速为8823 m·s-1,爆压为36.72 GPa。

英文摘要:
      A novel thermally stable energetic material ,4-amino-2,6-bis(5-amino-1H-tetrazol)-3,5-dinitropyridine(ABDP) was first synthesized via two-step reactions of nitration and condensation reaction using 4-amino-2,6-dichloropyridine as a raw material with a total yield of 36%, and its structure was characterized by nuclear magnetic resonance (NMR), mass spectrum (MS) and elemental analysis. Condensation reaction of 3-amino-1,2,4-triazole or 5-amino-1H-tetrazole and 4-amino-2,6-dichloro-3,5-dinitropyridine was investigated. Its thermal properties were studied by thermogravimetry(TG)and differential scanning calorimetry(DSC). Results show that similar nucleophilicity occurs at primary amine and secondary amine of 3-amino-1,2,4-triazole, but secondary amine in 5-amino-1H-tetrazole has higher nucleophilicity than that of primary amine. ABDP has a thermal decomposition peak at 323 ℃ accompanied with 94% mass loss. The detonation velocity and detonation pressure of 4-amino-2,6-bis(5-amino-1H-tetrazol)-3,5-dinitropyridine are predicted by Rothstein's method with the values of 8823 m·s-1 and 36.72 GPa, respectively.
