J Hazard Mater. 2003 Aug 29;102(2-3):147-53. doi: 10.1016/s0304-3894(03)00179-1.

Abstract

The thermal behavior, mechanism and kinetic parameters of the exothermic first-stage decomposition reaction of the title compound in a temperature-programmed mode have been 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 (1-alpha)(2), 178.41 kJ mol(-1) and 10(17.06)s(-1), respectively. The critical temperature of thermal explosion of the compound is 184.99 degrees C. The values of DeltaS( not equal ), DeltaH( not equal ) and DeltaG( not equal ) of this reaction are 91.54 J mol(-1)K(-1), 176.86 kJ mol(-1) and 135.83 kJ mol(-1), respectively.
