Abstract
Two energetic materials (2 and 4) were designed and synthesized from 3,5-diamino-1,2,4-triazole (DAT) and 3,5-diamino-4-nitropyrazole (DANP) as starting materials. Both of them were fully characterized by NMR spectroscopy, IR spectroscopy, and single-crystal X-ray diffraction analysis. Compounds 2 (Td = 295 °C) and 4 (Td = 300 °C) exhibit good thermal stabilities by differential scanning calorimetry. The detonation performances (2: D = 7281 m s–1, P = 18.6 GPa; 4: D = 7436 m s–1, P = 20.5 GPa) were calculated by EXPLO5 software. Their mechanical sensitivities (2: IS > 20 J, FS = 360 N; 4: IS > 20 J, FS = 360 N) were measured by BAM standard tests. Both 2 and 4 exhibited high thermal stabilities, insensitive characteristics, and fair detonation performances, which give them good potential as heat-resistant explosives.
