摘要

A new family of energetic salts based on a new guanidinium cation containing furoxanyl functionality, 1-(3'-methylfuroxanyl) methyleneamino guanidinium cation, were synthesized and well characterized by IR and multinuclear NMR spectroscopy, elemental analysis as well as differential scanning calorimetry. The structures of salts 1, 4, 5 and 6 were confirmed by single-crystal X-ray diffraction. Most of the salts decompose at temperatures over 180 degrees C. Furthermore, except for salts 7 and 9, the remaining energetic salts exhibit low impact sensitivities (15-40 J), friction sensitivities (120-360 N), and are insensitive to electrostatics. The detonation pressure values calculated for these salts range from 19.3 to 27.5 GPa, and the detonation velocities range from 7515 to 8402 m s(-1). These results make some energetic salts potential candidates for energetic materials with good thermal stabilities and low sensitivities.
