Nitrogen-Rich Substituent of Azo Furazan Compounds: Synthesis,Characterization and Performance

摘要

Virous new azo furazan derivatives containing oxadiazol, triazol and tetrazol group were synthesized by straightforward routes.These high nitrogen compounds were characterized by multinuclear NMR spectroscopy as well as mass spectrometry.Furthermore, the thermal stabilities and sensitivities were determined by differential scanning calorimetry (DSC) and standardized impact and friction tests.The densities of the azo furazan compounds ranged between1.62 g.em-3-1.85 g.cm-3 as measured by gas pyenometer and X-ray diffraction.Performance parameters including heats of formation and detonation properties were calculated by using the Gaussian 09 program based on the isodesmic reactions and EXPLO5 v6.02 programs, respectively.The present results suggest that the sensitivity of azo furazan derivatives to impact and friction coupled with their high thermal stability might be of interest for future applications as environmentally friendly and high performing nitrogen explosives.
