Energetic materials derived from nitration of 3-amino-4-chloroximefurazan

摘要

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, ~(13)C or~(15)N), IR spectroscopy and elemental analysis. Ammonium (lb), hydroxylammonium (2b) and aminoguanidinium salts (5b) were further confirmed by single-crystal X-ray diffraction. Additionally, their decomposition temperatures, impact sensitivities and friction sensitivities were determined. Among them, the dihydroxytammonium 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: 0B=-5.3%), which makes it promising high-performance energetic material.
