TACOT Derived New Nitrogen Rich Energetic Compounds: Synthesis, Characterization and Properties

Abstract

The nitrogen-rich structures of 2,4,8,10-tetranitrobenzo [4’,5’][1,2,3]triazolo[2’,1’:2,3][1,2,3]triazolo[4,5-b]pyridin-6-ium-5-ide (7) and 2,4-diazido-8,10dinitrobenzo[4’,5’][1,2,3]triazolo [2’,1’:2,3][1,2,3]triazolo[4,5-b]pyridin-6-ium-5-ide (8), have been designed, synthesized and characterized by IR spectrum, element analysis, differential scanning calorimetry (DSC) and single-crystal X-ray diffraction analysis. The decomposition temperatures of 7 and 8 are 366 °C and 181 °C, respectively. The detonation velocities and pressures of 7 and 8 were calculated by using EXPLO 5 (V6.04) based on their experimental densities and calculated heats of formation with results of 7670 m s-1, 24.19 GPa for 7, and 7167 m s-1, 19.70 GPa for 8, respectively. The sensitivities towards impact and friction of 7 and 8 are 9 J, >360 N and 5 J, 240 N, respectively. Meanwhile, compound 8 possesses good nitrogen content (47.76%), moderate decomposition temperature and excellent positive heat of formation at 1053 kJ mol-1. This study suggests 7 for a potential thermally-stable explosive and 8 for a nitrogen-rich high energetic material.
