Abstract: | The amino, azido, nitro, and nitrogen‐rich azole substituted derivatives of 1H‐benzotriazole have been synthesized for energetic material applications. The synthesized compounds were fully characterized by 1H and 13C NMR spectroscopy, IR, MS, and elemental analysis. 5‐Chloro‐4‐nitro‐1H‐benzo1,2,3]triazole ( 2 ) and 5‐azido‐4,6‐dinitro‐1H‐benzo1,2,3]triazole ( 7 ) crystallize in the Pca21 (orthorhombic) and P21/c (monoclinic) space group, respectively, as determined by single‐crystal X‐ray diffraction. Their densities are 1.71 and 1.77 g cm?3, respectively. The calculated densities of the other compounds range between 1.61 and 1.98 g cm?3. The detonation velocity (D) values calculated for these synthesized compounds range from 5.45 to 8.06 km s?1, and the detonation pressure (P) ranges from 12.35 to 28 GPa. |
