New Energetic Ionic Derivatives of Symmetric 4,6‐Dihydrazinium‐1,3,5‐Triazine‐2‐One Cation with Low Impact and Friction Sensitivities

Abstract A facile synthetic protocol was developed to synthesize unique energetic salts based on 4,6‐dihydrazino‐1,3,5‐triazine‐2‐one in good to high yield from commercial sources. The process was found to be practical and easily scalable. The resulting energetic compounds show good to excellent thermal stability with decomposition temperatures ranging from 180 °C to 331 °C. They possess low sensitivity to impact and friction (IS>20 J, FS>360 N), as well as positive enthalpy of formation (148.9∼1381.7 kJ mol−1). Their detonation velocity (VD) values locate between 8301 m s−1 and 9282 m s−1, and detonation pressure (P) values range from 26.1 GPa to 37.2 GPa, in some cases, which are comparable to those of HMX. From the view of sensitivity and energy level, some of the energetic compounds prepared in this work exhibit potential as insensitive excellent performance energetic materials.
