| 摘 要： | 用热失重法（thermogravimety, TG）、差示扫描量热(differential scaning calorimety, DSC）和跃迁升温（T-Jump）与快速扫描红外联用技术研究FOX-7热分解历程。结果表明,FOX-7热分解过程存在硝基和亚硝基重排,脱硝释放出NO，脱硝引起分子骨架的最后解体释放出 HNCO、HCN、NH3、CO2、CO等气体。获得了热分解阶段的活化能Ea= 246.65 kJ/mol, 指前因子lgA=23.81,初期阶段热分解反应为成核和生长反应, 反应级数为1.5。

| Abstract: | The thermal decomposition process of 1,1-diamino-2,2-dinitroethylene(FOX-7) was investigated by differential scaning calorimety(DSC),thermogravimety(TG) and T-Jump rapid scan-FTIR coupling techniques.Results show that the isomerization of the-NO_(2) group occurs and NO is released,and then the decomposition of main framework of FOX-7 liberates HNCO,HCN,NH3,CO_(2),CO,etc.The activation energy E_(a) is 246.65 kJ/mol,the factor in front of exponential lgA is 23.81.The pyrolysis mechanism of early stage of FOX-7 is the reaction of nuclear formation and development,and its reaction order is 1.5. |
