| 摘要: |
| 以3,6-对(3,5-二甲基吡唑)-S-四嗪(BT)为起始物，研究了S-四嗪类高氮含能化合物3-氨基-6-(3,5-二甲基吡唑)-S-四嗪(ADMPT)、3-肼基-6-(3,5-二甲基吡唑)-S-四嗪(HDMPT)、3,6-二氨基-S-四嗪(DATz)、3,6-二肼基-S-四嗪(DHTz)与3,3'-偶氮-(6-氨基-S-四嗪)(DAAT)的合成，经IR、元素分析、1HNMR、13CNMR等对其结构进行了表征和确认。对DHTz和DAAT的热分解性能进行了研究，由不同升温速率下的DSC实验获得了其热分解动力学参数。结果表明DAAT热稳定性好、能量高，在10℃/min升温速率下，DAAT在280℃开始分解，放热峰值330℃，放热峰的分解焓为1974.33J/g；DHTz在120℃开始分解，放热峰值159℃，放热峰的分解焓为1843.23J/g。同时，采用高温高压爆轰产物状态方程(VLW EOS)对DHTz和DAAT的爆轰性能进行了理论计算。 |

| Abstract: |
| 3-amino-6-(3,5-dimethylpyrazol-1-yl)-S-tetrazine(ADMPT), 3-hydrazino -6-(3,5-dimethylpyrazol-1-yl)-S-tetrazine(HDMPT), 3,6-diamino-S-tetrazine(DATz), 3,6-dihydrazino-S-tetrazine(DHTz), 3,3'-azobis(6- amino-S-tetrazine) (DAAT) and some S-tetrazine high-nitrogen energetic compounds were synthesized. The structures of these compounds were represented and confirmed by IR, element analysis, 1H NMR and 13CNMR spectra. The thermal decomposition performance of DAAT and DHTz was investigated. Kinetic parameters of decomposition were obtained by DSC at different heating rates. The results show that DAAT is stable up to 283℃, with maxima exotherm at 330℃ and ΔH of 1974.33J/g. DHTz is stable up to 120℃, with maxima exotherm at 159℃ and ΔH of 1843.23J/g. The explosive power performance of DAAT and DHTz was calculated by VLW EOS. |
