摘要 使用原位热红外光谱技术对FOX-7热分解全过程的气相和凝聚相产物进行了原位在线检测,通过非等温热红外动力学处理技术,获得了热分解过程中各特征官能团的断裂分解活化能:C-N键:181.7kJ·mol-1,-NO2键:235.8kJ·mol-1,N-H键:170.7kJ·mol-1。提出了FOX-7可能的两步热分解机理:第1阶段是分子共轭键、分子间(内)氢键的断裂、硝基和亚硝基重排“脱硝”释放出NO;第2阶段是残余碎片分解释放出HCN和NH3。 The whole process of the thermal decomposition of FOX-7 was investigated by thermolysis in-situ cell rapid man IR. The activation energy of C-N,-NO2, -NH is: 181.7kJ·mol^-1, 235.8kJ ·mol^-1 , 170.7kJ ·mol^-1 , which is obtained by using thermo-IR isothermal kinetic method. Two steps appears in thermal decomposition process of FOX-7. In the frist step the hydrogen bond dissociation and the isomerization of the -NO2 group occur and NO is released. The second step concludes the dissociation of the main bond of FOX-7 and at the same time HCN, NH3 are released.
