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 1.74 g cm(-3,) , respectively), acceptable impact and friction sensitivities (14 J, 160 N and 28 J, 360 N), and good detonation pressures (38.3 and 32.2 GPa) and velocities (9323 and 9094 m s(-1) ), have performance properties superior to 1,3,5-trinitro-1,3,5-triazinane (RDX) and triaminotrinitrobenzene (TATB).
