Abstract

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 -NO2 group occurs and NO is released ,and then the decomposition of main framework of FOX-7 liberates HNCO, HCN, NH3, CO2, CO, etc. The activation energy Ea 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.
