Abstract:

以1-氨基-2-硝基胍和4-硝胺基-1, 2, 4-三唑为原料, 制备了一种新型含能离子盐—1-氨基-2-硝基胍4-硝胺基-1, 2, 4-三唑盐, 并优化了反应条件。用TG-DSC研究了其热分解行为。结果表明, 在反应时间为4 h, 反应温度为50 ℃的优化合成条件下, 1-氨基-2-硝基胍4-硝胺基-1, 2, 4-三唑盐的产率最高为86.5%。该化合物在175.5 ℃左右剧烈分解, 显示热稳定性较好。利用Born-Haber循环求得该化合物的生成热为551.3 kJ·mol-1。测得该化合物的密度为1.59 g·cm-3。基于密度和生成热, 通过Kamlet-Jacobs公式得到该化合物的爆速和爆压分别为8.05 km·s-1和爆压26.6 GPa
