Synthesis and Properties of 3, 3′-Bis(trinitromethyl- ONN -azoxy)azoxyfurazan(BTNAF)

Using 3, 3′-bis(nitromethyl ONN azoxy)azoxyfurazan(BNMAF) as starting material, an excellent energetic compound 3, 3′-bis(trinitromethyl ONN azoxy)azoxyfurazan(BTNAF) was synthesized via two steps (nitration and second nitration)with a total yield of 68.7%. The thermal behavior of BTNAF was investigated by differential scanning calorimetry(DSC) for the first time (melting point: 59-61 ℃, decomposition point: 183.6 ℃, decomposition heat: 1989 J·g -1 ) The physicochemistry and detonation performances of 3, 3′-bis(nitromethyl ONN azoxy)azoxyfurazan(BNMAF), 3, 3′-bis(dinitromethyl ONN azoxy)azoxyfurazan(BDNAF) and BTNAF were fully analyzed and compared by Gaussian, which revealed that BDNAF (detonation velocity: 9560 m·s -1 ; detonation pressure: 42.40 GPa)and BTNAF (detonation velocity: 8944 m·s -3 ; detonation pressure: 38.48 GPa)were two promising energetic compounds with outstanding performances.
