Thermodynamic Analysis and Pyrolysis Mechanism of 4,4'-Azobis-1,2,4-triazole.

ABSTRACT: The nonisothermal thermal decomposition kinetics of 4,4'-azobis-1,2,4-triazole (ATRZ) at different heating rates (5, 10, 15, and 20 °C·min^-1) were investigated by thermogravimetry (TG) and differential scanning calorimetry (DSC) studies. The thermal decomposition kinetic parameters such as apparent activation energy (E) and pre-exponential factor (A) were calculated by the Kissinger, Ozawa, and Šatava-Šestak methods. The E and A values calculated by the above three methods are very close, which are 391.1 kJ·mol^-1/1034.92 s^-1, 381.1 kJ·mol^-1/1034.30 s^-1, and 393.4 kJ·mol^-1/1035.76 s^-1, respectively. Then, the decomposition mechanism function of ATRZ is analyzed by the calculated results.
