The thermal behavior, mechanism and kinetic parameters of the exothermic first-stage decomposition of the title compound in a temperature-programmed mode were investigated by means of DSC, TG-DTG and IR. The reaction mechanism was proposed. The kinetic model function in differential form, apparent activation energy(%E%-a) and pre-exponential factor(%A%) of this reaction are (3/2)(1-%α%)[-ln(1-%α%)]+{1/3}, 185^52 kJ/mol and 10+{17^78} s+{-1}, respectively. The critical temperature of the thermal explosion of the compound is 201^30 ℃. The values of Δ%S%+≠, Δ%H%+≠ and Δ%G%+≠ of this reaction are 72^46 J/(mol· K), 175^1 kJ/mol and 141^50 kJ/mol, respectively.
The thermal behavior, mechanism and kinetic parameters of the exothermic first-stage decomposition of the title compound in a temperature-programmed mode were investigated by means of DSC, TG-DTG and IR. The kinetic model function in differential form, apparent activation energy (% E % - a) and pre-exponential factor (% A %) of this reaction are (3/2) (1 - % alpha %) [- ln (1 - % α %) ] + {1/3 }, 185 ^ 52 kJ / mol and 10 + { 17 ^ 78 s + {- 1 }, respectively. The critical temperature of the thermal explosion of the compound is 201 ^ 30 ° C.
