Electrochemical Synthesis and Properties of Tetrazole-1,3,4-oxadiazole azo Energetic Compounds
摘要
Abstract
To promote the green development of energetic materials and improve their thermal stability and energy performance,the electrochemical synthesis of tetrazole-1,3,4-oxadiazole azo energetic compounds(H2AzAOT)and its metal salts(Mn-AzAOT,Zn-AzAOT,Pb-AzAOT)were studied by inserting the azoxadiazole ring block into the molecule.The structures of H2AzAOT and its metal salts were characterized by single crystal X-ray diffraction,infrared spectroscopy and nuclear magnetic resonance.The thermal stability,impact sensitivity and friction sensitivity were studied by differential scanning calorimetry and standard BAM method.The detonation performances were calculated by EXPLO5 program.The results indicate that H2AzAOT and its metal salts have excellent physicochemical properties.Among them,the theoretical detonation velocity(D)and detona-tion pressure(p)of H2AzAOT are 8511 m·s-1 and 28.9 GPa,respectively.The D and p of Pb-AzAOT are 8934 m·s-1 and 29.7 GPa,respectively.The detonation performances of both compounds are significantly better than that of the traditional heat-resistant and insensitive energetic material hexanitrostibene(HNS)(D=7612 m·s-1,p=24.7 GPa).关键词
