Property Study of Poly Nitro Compounds of cis-syn-cis-2,6-Dioxodecahydro-1H, 5H-diimidazo 4,5-b: 4', 5'-e Pyrazine

摘要

Poly nitro group substituted cis-syn-cis-2, 6-dioxodecahydro-1H, 5H-diimidazo [4, 5-b: 4', 5'-e] pyrazine derivatives are synthesized by modified method and adequately characterized. All compounds have good performance both in density (ρ> 1.85 g/cm~3) and high detonation velocity (v_D > 8800 m/s, calculated). Some representative compounds, for example, 4 (v_D: 9405 ms~(-1); P: 41.6 GPa) and 5 (v_D:9781 ms~(-1); P: 45.6 GPa) exhibit excellent detonation performances, which are comparable with current energetic compounds such as RDX (v_D: 8724 ms~(-1); P: 35.2 GPa) and HMX (v_D:9059 ms~(-1); P: 39.2 GPa). Considering the sensitivity increasing with the number of nitro group, two componds with tetranitro groups (2 and 3) are worthy of deep research.
