摘　　要：应用DSC/TG-MS-FTIR同步热分析-红外质谱联用技术,研究了ADN的分解过程及分解机理,从ADN分解生成的气体产物的动态分布及气体产物的生成动力学方面,获得了ADN热分解的主要气体产物为N2O、NO2、NH3、H2O和N2,气体产物N2O、NO2和NH3的动力学参数的Ea值分别为157.5、158.6、100.0 kJ/mol,从微观角度提出了ADN可能的热分解机理。The thermal decomposition process and mechanism of ADN were investigated by using DSC/TG-MS-FTIR technology together.During the thermal decomposition of ADN,N2O,NO2,NH3,H2O and N2 were detected in gas phase by simultaneous TG-DSC-FTIR-MS techniques.The kinetic parameters,activation energy Ea of N2O,NO2 and NH3 gas products are 157.5 kJ/mol,158.6 kJ/mol,100.0 kJ/mol respectively.The decomposition mechanism closely resembles the genuine elementary microcosmic processes.
