Abstract: : 2,3-dihydro-5,6,7,8-tetranitro-1,4-benzodioxine (TNBD), molecular formula =C8H4N4O10 is a completely nitrated in aromatic ring 1,4-benzodioxane derivative. The con-venient method of TNBD synthesis was developed (yield=81 %). detailed structure this compound has been investigated by X-ray crystallography. results differential thermal analysis (DTA) obtained with twice re-crystallized material showed onset at 247 and isoterm 288 0C, further total degradation 300 0C. experimental density 1,85 g/cm3 determined spectral properties (NMR, FT-IR, Ra-man) were explored. detonation calculated EXPLO 5 code slightly superior comparison to standard high energy - tetryl (detonation velocity 7727 m/s; pressure 278 kbar; – 7570 m/s 226.4 kbar 1.614 g/cm3, or 260 higher 1.71 g/cm3. preliminary might suggest can be potential thermostable (HEDM).
