| Abstract: | The thermal behavior of 4,6‐bis‐(5‐amino‐3‐nitro‐1,2,4‐triazol‐1‐yl)‐5‐nitropyrimidine (BANTNP) was studied under a non‐isothermal condition by DSC, PDSC and TG/DTG methods. The kinetic parameters (Ea and A) of the exothermic decomposition reaction are 304.52 kJ·mol?1 and 1024.47 s?1 at 0.1 MPa, 272.52 kJ·mol?1 and 1021.76 s?1 at 5.0 MPa, respectively. The kinetic equation at 0.1 MPa can be expressed as: dα/dT=1025.3(1?α)3/4exp(?3.8044×104/T)/β The critical temperature of thermal explosion is 588.28 K. The specific heat capacity of BANTNP was determined with a Micro‐DSC method, and the standard molar specific heat capacity is 397.54 J·mol?1·K?1 at 298.15 K. The adiabatic time‐to‐explosion of BANTNP was calculated to be 11.75 s. |
