Thermal behavior of 1,2,3-triazole nitrate

The thermal decomposition behaviors of 1,2,3-triazole nitrate were studied using a Calvet Microcalorimeter at four different heating rates. Its apparent activation energy and pre-exponential factor of exothermic decomposition reaction are 133.77 kJ mol −1 and 10 14.58 s −1 , respectively. The critical temperature of thermal explosion is 374.97 K. The entropy of activation (Δ S ≠ ), the enthalpy of activation (Δ H ≠ ), and the free energy of activation (Δ G ≠ ) of the decomposition reaction are 23.88 J mol −1 K −1 , 130.62 kJ mol −1 , and 121.55 kJ mol −1 , respectively. The self-accelerating decomposition temperature ( T SADT ) is 368.65 K. The specific heat capacity was determined by a Micro-DSC method and a theoretical calculation method. Specific heat capacity equation is (283.1 K
