Using 3, 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 characterized by NMR, IR, MS and elemental analysis. The optimized conditions of oxidation reaction were obtained as follows: reaction time 20-30 min, 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 calculated by Gaussian 09 and VLW equation of state for detonation. Results show that the maximum decomposition point is 295.5 ℃. The computed density is 1.765 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.
