A novel insensitive high explosive 3,4-Bis (aminofurazano) furoxan

A novel insensitive high explosive 3,4-bis (aminofurazano) furoxan (BAFF) was prepared using 3-amino-4-acylchloroximinofurazan (ACOF) as a precursor. The molecular and crystal structures of BAFF were characterized by IR, MS, ¹H NMR, ¹³C NMR, elemental analysis, and single crystal X-ray diffraction. The single crystal structure of BAFF recrystallized from water is monoclinic, space group P21/C, and ρ_c = 1.745g cm ^-3, and that recrystallized from ethanol is triclinic, space group P l, and ρ_c= 1.737 g cm^-3. BAFF has multiple crystal forms. The calculated detonation velocity by BKW code is 8100 m s^-1 (ρ = 1.795 g cm^-3, theoretical density calculated by quantum chemistry) and the experimental value is 7177 m s^-1 (ρ = 1.530 g cm^-3, charge density). The tested values of impact, friction, and electrostatic spark sensitivity show that BAFF is insensitive.
