Energetic salts based on 1-amino-1,2,3-triazole and 3-methyl-1-amino-1,2,3-triazole

Abstract

High-density energetic salts that contain nitrogen-rich anions and the 1-amino-1,2,3-triazole (ATZ) or 3-methyl-1-amino-1,2,3-triazole (MAT) cation were synthesized. All salts were fully characterized by IR spectroscopy, multinuclear (¹H, ¹³C) NMR spectroscopy, differential scanning calorimetry (DSC), and impact sensitivity. 1-Amino-1,2,3-triazolium 5-nitrotetrazolate, 3-methyl-1-amino-1,2,3-triazolium 5-nitrotetrazolate, and 3-methyl-1-amino-1,2,3-triazolium azotetrazolate crystallize in the triclinic space group P, as determined by single-crystal X-ray diffraction. Their densities are 1.688, 1.588, and 1.550 g cm⁻³, respectively. The measured densities of the other organic energetic salts range between 1.56 and 1.86 g cm⁻³. The detonation pressure (P) values calculated for these salts range from 21.2 to 37.3 GPa, and the detonation velocities (D) range from 7239 to 9082 m s⁻¹, making the salts potentially energetic materials.
