摘要
以5-氨基-3-硝基-1,2,4-三唑(ANTA)和1-氨基-3,5-二硝基-1,2,4-三唑(ADNT)为原料,设计、合成了一种新型C—N互联三唑化合物1-氨基-3-硝基-5-(5-氨基-3-硝基-1,2,4-三唑-1-基)-1,2,4-三唑(DANBT),采用IR、NMR、MS对其结构进行了表征,用差示扫描量热法研究了DANBT的热性能,确定了其熔点为221.8℃,分解峰温为291.8℃,热稳定性优于ADNT和ANTA。采用Kamlet-Jacobs方程预测DANBT的爆速与爆压分别为8.69 km·s-1,33.91 GPa。
A new C--N bitriazoles compound 1-amino-3-nitro-5-（5-amino-3-nitro-1,2,4-triazole-1-yl）-1 ,2,4-triazole （DANBT） was synthesized with 5-amino-3-nitro-1 ,2,4-triazole（ANTA） and 1-amino-3,5-dinitro-1 ,2 ,4-triazole （ADNT） as starting materi- als, and its structure and thermal performance were characterized by IR, MS, NMR and differential scanning calorimetry（DSC）, respectively. Results show that the melting point and decomposition peak temperature are 221.8℃ and 291.8 ℃, indicating that NANBT has better thermal stability than ANTA and ADNT. The detonation velocity and detonation pressure calculated with the Kamlet-Jacobs equation of DANBT are 8.69 km . s-1 and 33.91 GPa, respectively.
