| Abstract: | Thermal decomposition processes of TATB and DATB were investigated by using DSC, PDSC, TG ,TG-FTIR coupling technique and in-situ thermolysis rapid scan-FTIR coupling technique. Kinetic parameters of thermal decomposition were obtained, and mechanisms of thermal decomposition were presented. The results show that there exist some intermediate products in the initial thermal decomposition process of TATB and DATB, such as benzofurazan or benzofuroxan compounds. |
