The thermal behavior of 3,3-dinitroazetidinium hydrochloride (DNAZ路HCl) was studied at a nonisothermal condition by differential scanning calorimetric and thermogravimetric/differential thermogravimetric methods. The results show that there is only one intense exothermic decomposition process. Its kinetic parameters of the intense exothermic decomposition process are obtained from analysis of the DSC curves. The apparent activation energy (E_a), pre-exponential factor (A), and the mechanism function (f(伪)) are 155.72 kJ路mol^鈥?, 10^15.84 s^鈥? and 3伪^2/3, respectively. The specific heat capacity (C_p) of DNAZ路HCl was determined with a continuous C_p mode of microcalorimeter. The specific molar heat capacity (C_p,m) of DNAZ路HCl was 205.10 J路mol^鈥?路K^鈥? at 298.15 K. The self-accelerating decomposition temperature (T_SADT), thermal ignition temperature (T_TIT), and critical temperatures of thermal explosion (T_b) were obtained to evaluate the thermal stability and safety of DNAZ路HCl. The detonation velocity (D) and detonation pressure (P) of DNAZ路HCl were estimated using the nitrogen equivalent equation according to the experimental density. The stability, safety, and detonation performance of DNAZ路HCl were compared with that of 3,3-dinitroazetidinium 3,5-dinitrosalicylate (DNAZ路HClO₄).
