摘　　要：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4h,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BornHaber循环求得该化合物的生成热为551.3kJ·mol-1。测得该化合物的密度为1.59g·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8.05km·s-1和爆压26.6GPa。A novel energetic ionic salt 1-amino-2-nitroguanidinium4-nitroamino-1,2,4-triazole salt was synthesized using 1-amino-2-nitroguanidine and 4-nitroamino-1,2,4-triazole as the starting materials,and its reaction conditions were optimized.Its thermal decomposition behavior was investigated by TG-DSC.Its detonation properties were predicted using Kamlet-Jacobs formula.Results show that the yield of 1-amino-2-nitroguanidinium4-nitroamino-1,2,4-triazole salt is up to 86.5% under the optimum synthetic conditions of reaction time 4 h and reaction temperature 50℃.The compound decomposes sharply around175.5℃,revealing a better thermal stability.The heat of formation of the compound obtained by Born-Haber cycle is 551.3 kJ·mol^-1.The determined value of density is 1.59 g·cm^-3.Based on the heat of formation and density obtained,the detonation velocity and detonation pressure of the compound are8.05 km·s^-1 and 26.6 GPa,respectively.
