能离 3-氨基-5-肼基-1，2,4-三唑2,4,6- 三 基- 苯三酚的 性能研

A novel energetic ionic salt 3-amino-5-hydrazino-1,2,4-triazolium trinitro-phloroglucinolate(AHTr·TNPG)with two cations and two anions was synthesized by diazo, reduction and salt formation by using 3,5-diamino-l,2,4-triazole as raw material. The energetic ionic salt was characterized by single-crystal X-ray diffraction, FTIR, nuclear magnetic resonance spectroscopy, mass spectra and elemental analysis. The thermal decomposition behavior was investigated through DSC and TG-DTG technologies. The mechanical sensitivities was tested and the detonation parameters were calculated by Gaussian 09 program and EXPLO5(V6.04)detonation software. The results show that the crystal of AHTr·TNPG belongs to monoclinic system with space group Cc. It has a high crystal density of 1.807g/cm3 with decomposition temperature of 174℃. The calculated detonation velocity and pressure were 8475m/s and 30.4GPa, respectively. It exhibits low mechanical sensitivity with friction sensitivity of 324N and impact sensitivity of 30J. AHTr·TNPG has much higher detonation performances than those of traditional energetic compounds TNT and TATB, and approach to RDX. The above merits make AHTr·TNPG a promising high energy insensitive explosive.
