In this paper, the synthesis of N,N’-Bis(nitrobenzodifuroxan) oxalic amide is described in detail. 3,3’, 5,5’-Tetrachlo -2,2’, 4,4’,6, 6’- hexanitrooxanilide（Ⅰ） reacted with sodium azide in DMF-water to give 3,3’, 5,5’-Tetraazido -2,2’, 4,4’,6, 6’- hexanitrooxanilide (Ⅱ) at room temperature in 79.8% yield. N, N’-bis (nitrobenzodifuroxan) oxalic amide（Ⅲ） was obtained in 79.1％ yield from (Ⅱ) and in propionic acid through denitrogenation at 110℃. The decomposing point of (Ⅲ) is 220℃. The structures of N, N’-bis (nitrobenzodifuroxan) oxalic amide has been determined by IR, MS and elemental analysis. The target compound has a density of 1.86g?cm-3 found, a detonation velocity of 8.529km?s-1, and a detonation pressure of 33.31GPa. The impact sensitivity (h50) is 70.02cm which is predicted by the oxygen balance index (OB100).
