晶胞内嵌H2O2分子的CL-20基主客体炸药的温和制备
A Mild Method for the Construction of CL-20/H2O2 Host-guest Energetic Material
摘要
Abstract
Hexanitrohexaazaisowurtzitane(CL-20)with a negative oxygen balance,is currently the most powerful commercially available explosive. In this work,the CL-20/H2O2 host-guest energetic material(CL-20/H2O2)was constructed by using urea hy-drogen peroxide(UHP)as raw material through the solvent volatilization at low temperature and negative pressure. The struc-ture of the complex was confirmed through X-ray diffraction(XRD)and Raman spectra. Results indicates that CL-20/H2O2 crystal-lizes in orthorhombic system space group Pbca with a long-range ordered stacked structure. The ratio of CL-20 molecule and H2O2 molecule is 2:1 stoichiometry according to the thermogravimetry and simultaneous differential scanning calorimetry (TG-DSC)analyses. Furthermore,the polymorph transitions of CL-20/H2O2 with increasing temperature were investigated by in situ high temperature XRD. Results show that CL-20/H2O2 gradually converts to γ-CL-20 with elevated temperature and the rate of transition is faster than that of ε-CL-20. The CL-20 acetonitrile solvate(CL-20/CH3CN)is a key intermediate via a solid state phase transition to form the CL-20/H2O2 host-guest energetic material by tracing the growing process of CL-20/H2O2.关键词
