摘要

以3,3'-双[单硝甲基-ONN-氧化偶氮基]氧化偶氮呋咱为原料,经过硝化,二次硝化两步反应合成了3,3'-双[三硝甲基-ONN-氧化偶氮基]氧化偶氮呋咱(BTNAF),总收率为68.7％;首次利用示差扫描量热法(DSC)研究了BTNAF的热行为,其熔点为59～61℃,分解温度为183.6℃,放热量为1989 J·g-1;通过高斯计算,对比了BNMAF,BDNAF和BTNAF的物化性能和爆轰性能,结果表明,BDNAF(爆速9560 m·s-1,爆压42.40 GPa)和BTNAF(爆速8944 m·s-3,爆压38.48 GPa)是潜在的性能突出的含能化合物.%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:1 83.6 ℃,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 B DNAF (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.
