Abstract:
Achieving a balance of good thermal stability, high performance, and appropriate sensitivity in materials remains a primary research goal in energetic materials. In this study, a series of dinitrimine-functionalized tris-1,3,4-oxadiazole-based energetic compounds was synthesized. Dinitroimmine 5 was found to possess favorable thermal stability (Td = 180 °C), superior mechanical sensitivity (IS = 25 J, FS = 240 N), and good detonation velocity (vD = 8372 m s-1). These results suggest that this polyheterocyclic backbone structure facilitates the synthesis of high-performance energetic compounds with application potentials.

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by...
