Synthesis and Properties of Insensitive Energetic Compound Based on Methyl-Bridged Triazole-Oxadiazole
摘要
Abstract
By using 5-amino-3-nitro-1,2,4-triazole(ANTA)as raw material,a new methyl-bridged nitrogen-oxygen heterocyclic energetic compound 3-((5-amino-3-nitro-1H-1,2,4-triazol-1-yl)methyl)-1,2,4-oxadiazol-5-amine(3)was synthesized through a three-step reaction.The reaction conditions,including solvent,reaction temperature,and reaction time,were thoroughly in-vestigated.Compounds 1-3 were characterized by nuclear magnetic resonance(NMR),fourier-transform infrared spectroscopy(FT-IR)and elemental analysis(EA).Single crystal X-ray diffraction analysis was also performed on compound 3.The properties of compound 3 were studied by vacuum densitometer,thermogravimetric differential scanning meter and impact/friction sensitiv-ity meter.The theoretical detonation performances of compound 3 were calculated by Gaussian software.Results show that the total yield of compound 3 is 35.4%based on ANTA.The crystal packing of compound 3 belongs to the monoclinic system,space group P21/c,and each cell contains four molecules(Z=4)with a large number of intramolecular and intermolecular hy-drogen bonds.The density of compound 3 is 1.68 g·cm-3,the decomposition temperature is 232.2℃,the friction sensitivity is above 360 N,and the impact sensitivity is above 40 J.The theoretical detonation velocity and pressure of compound 3 are 7196 m·s-1 and 22 GPa,respectively,which are better than that of the traditional explosive TNT(D,6881 m·s-1;p,21.3 GPa).关键词
