Bis(4‐nitraminofurazanyl‐3‐azoxy)azofurazan and Derivatives: 1,2,5‐Oxadiazole Structures and High‐Performance Energetic Materials
Abstract
Bis(4‐nitraminofurazanyl‐3‐azoxy)azofurazan (1) and ten of its energetic salts were prepared and fully characterized. Computational analysis based on isochemical shielding surface and trigger bond dissociation enthalpy provide a better understanding of the thermal stabilities for nitramine‐furazans. These energetic compounds exhibit good densities, high heats of formation, and excellent detonation velocity and pressure. Some representative compounds, for example, 1 (vD: 9541 m s−1; P: 40.5 GPa), and 4 (vD: 9256 m s−1; P: 38.0 GPa) exhibit excellent detonation performances, which are comparable with current high explosives such as RDX (vD: 8724 m s−1; P: 35.2 GPa) and HMX (vD: 9059 m s−1; P: 39.2 GPa).
