摘要

A series of new energetic salts based on 4-nitro-3-(5-tetrazole)-furoxan (HTNF) has been synthesized. All of the salts have been fully characterized by nuclear magnetic resonance (~1H and ~(13)C), infrared (IR) spectroscopy, elemental analysis, and differential scanning calorimetry (DSC). The crystal structures of neutral HTNF (3) and its ammonium (4) and N-carbamoylguanidinium salts (9) have been determined by single-crystal X-ray diffraction analysis. The densities of 3 and its nine salts were found to range from 1.63 to 1.84gcm~(-3). Impact sensitivities have been determined by hammer tests, and the results ranged from 2 J (very sensitive) to >40J (insensitive). Theoretical performance calculations (Gaussian 03 and EXPLO 5.05) provided detonation pressures and velocities for the ionic compounds 4-12 in the ranges 25.5-36.2 GPa and 7934-8919 ms~(-1), respectively, which make them competitive energetic materials.
