Abstract
A new nitrogen-rich energetic salt, 2,4-diamino-6-methyl-1,3,5-triazine dinitramide, was synthesized by combining silver dinitramide and 2,4-diamino-6-methyl-1,3,5-triazine perchlorate. The structure of this new energetic salt was confirmed using single-crystal X-ray diffraction, elemental analysis, Fourier transform infrared spectrometry, ultraviolet–visible spectrophotometry, and nuclear magnetic resonance spectroscopy. The thermal stability was determined using differential scanning calorimetry, differential thermal analysis, and thermogravimetric tandem infrared spectrometry. Results showed that the target compound exhibits good thermal decomposition resistance of up to 470 K and has 59.1% mass loss with Ea = 118.2 kJ mol−1. Additionally, the detonation pressure and velocity obtained using Kamlet-Jacobs equations are 23 GPa and 8.2 km s−1, respectively. Sensitivity test was also attempted. The impact sensitivity of this new energetic salt is 11.5 J, which is superior to that of RDX (7.4 J).
