Promising Nitrogen and Oxygen-rich Tetrazole and Its Energetic Salts-Synthesis, Characterization and Thermal Properties
Two series of energetic salts with nitrogen and oxygen-rich skeleton, hydroxytetrazole, and detonation units were synthesized by convenient routes via available commercial reagents. The obtained energetic materials were investigated via IR, NMR and X-ray diffraction. Meanwhile, the electrostatic potential, detonation performance, along with DSC - TG - IR - MS analysis, were comprehensively investigated. The synthesized energetic salts exhibit convincing physical-chemical and detonation properties (Densities range from 1.70 g·cm -3 to 1.92 g·cm -3 . Detonation velocities up to 9500 m·s -1 ). The obtained materials display a decent thermal and mechanical stability. The decomposition temperatures of most of salts are close to 200 °C. The impact and friction sensitivities can surpass 40 J and 360 N respectively. Also the thermal decomposition mechanism was clarified. In general, novel series of energetic materials with promising performance are synthesized, which make their great application in the propellant field possible.
