3,3‐Dinitroazetidinium 3,5‐dinitrobenzoate (DNAZ ⋅ DNB) was synthesized, its thermal behavior was studied under a non–isothermal condition by DSC and TG/DTG methods. The intense exothermic decomposition process of DSC curves were analyzed to obtain its kinetic parameters. The specific molar heat capacity ( C p ,m ) of DNAZ ⋅ DNB was determined by a continuous C p mode of micro−calorimeter, and the value was 416.81 JK −1 mol −1 at 298.15 K. Its detonation velocity ( D ) and detonation pressure ( P ) were estimated using the nitrogen equivalent equation according to the experimental density. The above results of DNAZ ⋅ DNB were compared with those of 3,3‐dinitroazetidinium 3,5‐dinitrosalicylate (DNAZ ⋅ DNS) and 3,3‐dinitroazetidinium picrate (DNAZ ⋅ PA), and the effect of phenolic hydroxyl, carboxyl, and nitro group on them were discussed.
