1‐ t ‐Butyl‐3,3‐dinitroazetidinium perchlorate (TDNAZ ⋅ HClO 4 ) was synthesized, DSC and TG/DTG methods were used to study the thermal behavior of TDNAZ⋅HClO 4 under a non–isothermal condition. The intense exothermic decomposition process of DSC curves were analyzed to obtain its kinetic parameters. Continuous specific heat capacity ( C p ) mode of micro–calorimeter was used to determine its C p , its specific molar heat capacity ( C p ,m ) was 365.70 J mol −1 K −1 at 298.15 K. The self‐accelerating decomposition temperature ( T SADT ), thermal ignition temperature ( T TIT ), and critical temperature of thermal explosion ( T b ) were obtained to evaluate its thermal stability and safety. The above results of TDNAZ ⋅ HClO 4 were compared with those of 3,3‐dinitroazetidinium perchlorate (DNAZ ⋅ HClO 4 ), and the effect of tert‐butyl group on them was discussed.
