Abstract

Abstract: Differential scanning calorimetry (DSC) technique is used to study the thermal decomposition and safety parameters of 3-nitro-1,2,4-triazol-5-one (NTO). The “interruption and rescanning” and Swiss methods are used to evaluate the autocatalytic effect during thermal decomposition of NTO, which was verified by isothermal DSC experiments. The decomposition kinetic parameters of NTO are determined by using the Friedman isoconversional method. The kinetic parameters with heat balance are analyzed and used to estimate the time to the maximum reaction rate under adiabatic conditions (TMR_a). The results show that the initial thermal decomposition temperature of NTO is in the range of 249.4- 271.2 ℃ at the heating rates of 2, 5, 10 and 20 ℃/min, and the decomposition reaction of NTO is an autocatalytic reaction. Thermal history has significant influence on the thermal stability of NTO, where the preheating would decrease its initial thermal decomposition temperature and the peak temperature. T₈ and T₂₄ of NTO are 166.1 and 152.1 ℃, respectively. Key
