| 摘 要： | 用热重-微商热重分析(TG-DTG)、热重与傅立叶变换红外联用技术(TG-FITR)、热重与质谱联用(TG-MS)和热裂解快速扫描付里变换红外技术(RCFT-IR)法研究了1-甲基-2,4,5-三硝基咪唑(MTNI)热分解过程和热分解反应动力学,根据实验结果,提出了MTNI的热分解机理:MTNI的放热分解过程分两个阶段,第一阶段是—NO2基发生明显变化,生成NO;第二阶段是芳环断裂分解,释放出H2O、CO、CO2、NO2等气体。

| Abstract: | Thermal decomposition and kinetics of 1-methyl-2,4,5-trinitroimidazole(MTNI) were studied by using TG-DTG,TG-FITR,TG-MS and RCFT-IR in situ thermolysis cell or fast thermolysis probe with rapid-scan Fourier transform infrared spectroscopy(thermolysis/RSFT-IR and fast thermolysis/RSFT-IR) methods,respectively.Results show that the exothermic decomposition process can be derived into two steps: the rupture of the O—NO bond and ring breaking.The main products of thermal decomposition detected by TG-MS method were NO2,CO,CO2 and H2O.On the basis of experimental results,the thermal decomposition mechanism of MTNI is outlined. |
