Synthesis, Crystal Structure and Properties of a Novel Energetic Material Dirubidium 5, 5'-Bis(tetrazole-1-oxide)
摘要
Abstract
A new energetic material dirubidium 5,5'-bis (tetrazole-1-oxide) (BTORb) was synthesized by using 1 H,1'H-5,5'-bistetrazole-1,1'-diolate (BTO) as the original material.The monocrystal of target salt was first cultivated by the method of gradual evaporation,and the single crystal structure was menstruated by single X-ray diffraction.It is found that the Rb+ and BTO2-formed a dissymmetrical structure.In different layers,they are alternately arranged and connected with each other,forming a three-dimensional reticular structure.Its thermal decomposition behavior was investigated through DSC and TG-DTG technologies,indicating a good thermal stability with a decomposition temperature beginning at 292 ℃.Its kinetic parameters of non-isothermal reaction was calculated by Kissinger and Ozawa methods with the equation of Arrhenius is Ink=13.51-186.3 ×103/RT.Its standard heat of formation was calculated with the result of 274.91 kJ · mol-1.Its critical temperature of thermal explosion Tb is 356.7 ℃,indicating that the salt has a good thermal stability.The impact sensitivity (H50) of BTORb is 34.8 cm,with the drop hammer of 800 g.The friction sensitivity is 36％,under the condition of 70°,1.23 MPa.The 50％ fire energy of electrostatic spark sensitivity is 0.34 J.关键词
