Under linear temperature increase condition the thermal behavior and kinetic parameters of the exothermic fmt‐stage decomposition reaction of the title compound were studied by means of DSC and TG‐DTG. The empirical kinetic model function in differential form, apparent activation energy and pre‐exponential constant of this reaction are α 0.122 (1−α) 0.528 , 216.4 kJ·mol −1 and 1020.51 s −1 respectively. The critical temperature of thermal explosion of the compound is 222.25 °C. The values of Δ ≠ S , Δ ≠ H , and Δ ≠ G and of this reaction are 108.3 J·mol −1 K −1 , 205.1 kJ·mol −1 and 151.4 kJ·mol −1 , respectively.
