Synthesis and Characterization of 4,4,8,8-Tetranitro-2,6-dioxaadamantane
摘要
Abstract
A novel cage-like energetic compound,4,4,8,8-tetranitro-2,6-dioxaadamantane,was synthesized via four steps in-volving oxidative cyclization,oxidation,oximation and gem-dinitration by using 9-oxabicyclo[3.3.1]nona-2,6-diene as raw ma-terial.Its structure was characterized by nuclear magnetic resonance(NMR),Fourier transform infrared spectroscopy(FT-IR)and elemental analysis(EA),and single crystal X-ray diffraction(SC-XRD)was adopted to further confirm its crystal structure.The thermal stability was investigated by differential scanning calorimetry-thermogravimetry(DSC-TG)analysis,and detonation parameters were predicted by EXPLO5.Results show that 4,4,8,8-tetranitro-2,6-dioxaadamantane has a crystal density of 1.75 g·cm-3 and belongs to monoclinic system,space groups P21/c.Its thermal decomposition temperature is 190.6℃,theoreti-cal detonation velocity is 7705 m·s-1,and detonation pressure is 25.75 GPa.关键词
