Preparation, crystallographic characterization, and analysis of 3-amino-1,2,4-triazolium nitrate synthesized via electrolytic oxidation with ammonium nitrate

Electrolytic oxidation of 3-amino-1,2,4-triazole with ammonium nitrate as electrolyte yielded single crystals of 3-amino-1,2,4-triazole nitrate salt, which was previously reported but lacked structural and thermal data. In this work, we employ thermal and other analyses to better characterize the aforementioned salt. The salt released significantly more heat (2359 J/g) than the raw materials (909, and 1171 J/g, respectively) or their mixture (2112 J/g) in SC-DSC measurements. TG-DTA measurements revealed that a higher onset temperature of weight loss for the salt, although complete gasification was unobserved. Crystallographic data enabled calculations of the detonation velocity, which ranged from 7834 to 8101 m/s.
