Energetic Salts Based on Furazan-Functionalized Tetrazoles: Routes to Boost Energy

Based on the backbone of the furazan-tetrazole structure, routes were developed to improve the properties of energetic materials. Two types of high-density energetic salts were designed, prepared, and fully characterized. Single-crystal X-ray analyses support the structural characteristics for two amino salts. A majority of the salts exhibited good detonation properties, high thermal stabilities, and relatively low impact and friction sensitivities. Hydroxylammonium and hydrazinium salts, 1-3 and 1-4, which have relatively high densities (1.84 and 1.74gcm(-3,), respectively), acceptable impact and friction sensitivities (14J, 160N and 28J, 360N), and good detonation pressures (38.3 and 32.2GPa) and velocities (9323 and 9094ms(-1)), have performance properties superior to 1,3,5-trinitro-1,3,5-triazinane (RDX) and triaminotrinitrobenzene (TATB).
