Synthesis and Characterization of Nitromethyl-Substituted Bitetrazole Energetic Compounds
摘要
Abstract
Bistetrazole has become a research focus in the field of energetic materials due to its 80%nitrogen content and excel-lent detonation performance.However,its poor stability seriously restricts practical engineering applications.In this work,5,5'-bistetrazole diammonium salt was used as the starting material,and bromonitromethane was grafted onto the bistetrazole skeleton via nucleophilic substitution reaction.A novel nitromethyl-substituted bistetrazole energetic compound 1 with signifi-cantly improved stability,which can be potentially used in eutectic systems,was successfully synthesized.The structure of compound 1 was characterized by nuclear magnetic resonance spectroscopy(NMR),elemental analysis(EA),and infrared spec-troscopy(IR).Its precise crystal structure was further determined by single-crystal X-ray diffraction:the compound crystallizes in the monoclinic system,space group C2/c,with cell parameter Z=8 and crystal density 1.683 g·cm-3.Performance test results show that compound 1 exhibits an impact sensitivity of 15 J,friction sensitivity of 324 N,detonation velocity of 8325 m·s-1,and detonation pressure of 28.4 GPa,demonstrating superior overall performance compared to TNT(Dv=6881 m·s-1,p=19.5 GPa,IS=15 J,FS=353 N).关键词
