Two Energetic Ionic Salts of en·PA·H₂O and en·TNR: Preparation, Structural Characterization, and Properties

Energetic salts of en·PA·H₂O and en·TNR were synthesized by using ethylenediamine and picric acid (PA) or 2,4,6-trinitroresorcinol (TNR) as raw materials, and their structures were characterized by elemental analysis and FT-IR spectroscopy. Single crystals of the title salts were obtained and their structures were determined by single-crystal X-ray diffraction. The thermal decomposition behaviors were investigated by DSC and TG-DTG technologies, furthermore the non-isothermal kinetic parameters and enthalpies of formation for the salts were calculated. Their combustion heats were measured by oxygen bomb calorimetry and their enthalpies of formation were also calculated based on the combustion heat data. In addition, the detonation pressure (P) and detonation velocities (D) of the salts were predicted by using the K-J equations. The results indicated that the title salts have potential applications in the field of energetic materials.
