Anovel high performance explosive compound, N,N`-bis(1,2,3,4-tetrazol-5-yl)-4,4'-diamino-2,2',3,3',5,5',6,6'-octanitroazobenzene (BTeDAONAB), is introduced which is a thermally stable, insensitive high explosive. The presence of -NH2, -N=N groups and the tetrazole ring simultaneously in the BTeDAONAB unit surprisingly increases its thermal stability. For the identification and characterization of BTeDAONAB, different analytical techniques have been used, including melting point, IR, H-1 NMR, C-13 NMR spectroscopy, elemental analysis, differential thermal analysis (DTA), thermogravimetry (TG), differential scanning calorimetry (DSC) and X-ray diffraction (XRD). The sensitivity and detonation properties of BTeDAONAB were compared with 2,4,6-triamino-1,3,5-trinitrobenzene (TATB) and N,Nr-bis(1,2,4-triazol-3-yl-)-4,4'-diamino-2,2',3,3',5,5',6,6'-octanitroazobenzene (BTDAONAB), two well-known, thermally stable, insensitive high explosives, as well as hexanitrostilbene (HNS). These studies show that BTeDAONAB has favorable thermal stability with high performance.
