| 摘要: 本文通过3，6-二肼基-1，2，4，5-四嗪(DHT)分别与高氯酸和硝酸反应得到2种高氮含能离子盐，并通过X-射线单晶衍射技术对它们的结构进行了表征。(DHT)(NO3)2(1)属于单斜晶系，C2/c空间群，晶胞参数：a=1.300 0(6) nm，b=0.834 9(3) nm，c=1.018 7(5) nm，β=118.89(5)°，Z=4；(DHT)(ClO4)2(2)属于正交晶系，P21212空间群，晶胞参数：a=0.980 4(4) nm，b=1.074 7(4) nm，c=0.532 5(2) nm，Z=2。采用DSC和TG-DTG技术研究了这两种含能离子盐的热分解机理，并对这两种含能离子盐的非等温动力学、爆热及感度进行了测试分析。研究表明这两种含能离子盐在敏感型含能材料领域具有潜在的应用前景。 | |

| Abstract: Two high-nitrogen energetic salts were prepared by reacting 3,6-dihydrazino-1,2,4,5-tetrazine (DHT) and perchloric acid or nitric acid aqueous solution. Their structures have been determined by using X-ray single crystal diffraction method. (DHT)(NO3)2 (1) belongs to monoclinic, C2/c space group, a=1.300 0(6) nm, b= 0.834 9(3) nm, c=1.018 7(5) nm, β=118.89(5)°, Z=4; (DHT)(ClO4)2(2) belongs to orthorhombic, P21212 space group, a=0.980 4(4) nm, b=1.074 7(4) nm, c=0.532 5(2) nm, Z=2. The thermal decomposition was investigated with DSC and TG-DTG measurement. The non-isothermal kinetic parameters of the first exothermic process were studied by applying Kissingers, Ozawa-Doyles and Starinks methods. The critical temperature of thermal explosion and sensitivity properties also have been fully investigated. We can come to the conclusion that the two salts have potential application in sensitive energetic material area. CCDC: 884111, 1; 884112, 2. | |
