Abstract:

A new energetic ionic salt1,2,3-triaminoguanidinium dinitroguanidinate salt was synthesized based on 1,2,3-triaminoguanidinium hydrochloride and dinitroguanidine. The optimized structure, IR spectrum and thermodynamic parameters were obtained at the DFT-B3LYP/6-31+G** theoretical level. Its detonation properties were also predicted by the formula of Kamlet-Jacobs. The results show that the density, heat of formation, detonation velocity and detonation pressure are 1.56 g/cm3, 150.54 kJ/mol, 7.81 km/s and 24.74 GPa, respectively.
