Synthesis, Characterization, and Thermal Decomposition of a New Energetic Salt 3-Amino-1,2,4-Triazole Dinitramide

Abstract

ABSTRACTA new energetic salt, 3-amino-1,2,4-triazole dinitramide (ATADN), was synthesized through the combination of 3-amino-1,2,4-triazole cation and oxygen-rich dinitramide anion. The structure of ATADN was confirmed by single-crystal X-ray diffraction, elemental analysis, Fourier transform infrared spectroscopy, ultraviolet–visible spectrometry, and nuclear magnetic resonance spectroscopy. The thermal stability of ATADN was studied using differential scanning calorimetry, thermogravimetric analysis (TG), and TG tandem infrared spectrum. The thermal decomposition kinetics parameter was also calculated using the differential thermal analysis data based on Kissinger’s method. Results indicated that ATADN exhibited resistance to thermal decompositions of up to 439 K, and a corresponding activation energy of Ea = 281.9 kJ·mol−1. Moreover, its mechanical sensitivity and detonation properties were evaluated, which showed promising results for its potential application as a highly explosive compound.
