摘　　要：以3,4-双（3＇-氨基呋咱-4＇-基）呋咱（BATF）为原料,经氧化反应合成了未见文献报道的含能化合物双3,3＇-偶氮双（3-氨基三呋咱）（ABATF）,收率82%;采用红外、核磁、质谱以及元素分析等对目标化合物进行了表征;确定了氧化反应的最佳条件为加料时间20-30 min,BATF和KMn O4摩尔比1∶1,反应温度50℃;采用差示扫描量热法和热重-微商热重研究了ABATF的热行为,其最大放热峰温为295.5℃。通过Gaussian 09程序和VLW状态方程计算了ABATF的物化和爆轰性能,其密度为1.765 g·cm-3、爆速8250 m·s-1、生成焓1626.6 k J·mol-1、爆压为29.4 GPa、爆热为6350 J·g-1,综合性能优于BATF。Using3,4-bis（3＇-aminofurazan -4＇-yl） furazan （BATF） as starting material, a novel energetic compound 3,3＇-azobis （3-amino-trifurazan） （ABATF） was synthesized by oxidation reaction, with the yield of 82%. The structure of ABATF was charac- terized by NMR, IR, MS and elemental analysis. The optimized conditions of oxidation reaction were obtained as follows： reaction time 20-30 rain, molar ratio of BATF to KMnO4 1 ： 1 , reaction temperature 50 ℃. Thermal properties of ABATF were studied by differential scanning calorimetry and thermogravimetry-differential thermogravimetric. The detonation performances were calcu- lated by Gaussian 09 and VLW equation of state for detonation. Results show that the maximum decomposition point is 295.5 ℃. The computed density is I. 765 g · cm-3 , explosion velocity is 8250 m · s-1 , enthalpy of formation is 1626.6 kJ · mol -1 , detonation pressure is 28.4 GPa and explosion heat is 6350 J·g-1 , indicating that the performance of ABATF is better than BATF.
