Abstract

Flash pyrolysis of a thin film of lead salt of 3-nitro-1,2,4-triazol-5-one was studied by T-jump/FTIR spectroscopy. The kinetics of the exothermic decomposition reaction was determined by the time-to-exotherm (t_x) value derived from the control voltage traces of the Pt filament. The global Arrhenius activation energy E_a was 94.0 kJ · mol^-1 and InA was 20.5 for the flash pyrolysis of this compound at 500-540 K under 0.1 MPa Ar atmosphere. The corresponding Gibbs energy, entropy and enthalpy of the hypothetical activated process of exothermic decomposition reaction for the flash pyrolysis were determined approximately. The values determined herein could be used in evaluation of the thermal stability under rapid heating conditions and could be incorporated into steady combustion modelling.
