As an energetic material, 3,4-bis(4-nitrofurazan-3-yl)-furazan NTF was synthesized using dicyanopropane as original material through nitrosation, rearrangement, oximation, dehydration cyclization, dimerization, reduction and oxidation, with total yield of 29%, melting point was 86-87℃. Its molecular structure was confirmed by IR, NMR, MS and elemental analysis. The detonation properties were estimated with the Kamlet-Jacobs equations based on the predicted density and enthalpy of formation. The resuls showed that density was 1.80 g/cm3, heat of formation was 933.18 kJ/mol, detonation velocity was 8610 m/s, detonation pressure was 33 GPa. Because of its high energy, low melting point, moderate mechanical sensitivity, NTF could be probably used as an effective liquid-phasecarrier in melt-cast explosives.
