Materials with good energetic properties resulting from the smart combination of nitramino and dinitromethyl group with furazan

Abstract

In order to develop energetic materials with better comprehensive properties, energetic salts based on bifunctionalized furazan with nitramino and dinitromethyl group were synthesized and fully characterized by multinuclear NMR (¹H, ¹³C or ¹⁵N), IR spectroscopy and elemental analysis. Ammonium (1b), hydroxylammonium (2b) and aminoguanidinium salts (5b) were further confirmed by single-crystal X-ray diffraction. In addition, their decomposition temperatures, impact sensitivities and friction sensitivities were determined. Among the salts, dihydroxylammonium DNMNAF (2b) showed the best comprehensive properties (2b: d = 1.930 g cm⁻³; T_d = 175 °C; P = 43.0 GPa; v_D = 9646 m s⁻¹; IS = 8 J; FS = 64 N; OB = −5.3%), which makes it a promising high-performance energetic material.
