Ethylene Linked 4-Amino-3,5-dinitropyrazolated Moiety and Diverse Explosophore Groups:Synthesis,Characterization and Performances
摘要
Abstract
A family of ethylene-bridged energetic compounds containing 4-amino-3,5-dinitropyrazolated moiety and diverse explosophore groups were designed and synthesized by using 4-bromo-3,5-dinitropyrazole as raw material.The structures were characterized by NMR and single crystal X-ray diffraction.Their thermal decomposition properties were measured and detona-tion performances were predicted by Gaussian 09 program and EXPLO5 software.The results show that these new energetic compounds exhibit good thermal stability with thermal decomposition temperature ranging from 167.3℃to 294.1℃,and low mechanical sensitivities with impact sensitivity not less than18 J and friction sensitivity not less than 240 N.The theoretical deto-nation velocity and detonation pressure are ranging from 7 939 to 8448m/s and 25.0GPa to 30.8GPa,respectively.关键词
