Abstract:3,6-Dinitroimino[1,2,4]triazolo[4,3-b][1,2,4]triazole was synthesized through the nitration reaction of 3,6-diamino[1,2,4]triazolo[4,3-b][1,2,4]triazole with a yield of 80%. The structure of this product was fully characterized by infrared spectroscopy (IR), mass spectrum, 1H and 13C nuclear magnetic resonance (NMR) and elemental analysis. Its physiochemical properties were determined and theoretical detonation parameters were also calculated. It decomposes at 121 ℃, its density is 1.82 g/cm3 and impact sensitivity is less than 2 J, while the theoretical detonation velocity and pressure are 8789 m/s and 32.5 GPa, respectively. |
