Abstract

Abstract : In order to develop high energy density materials, 5, 5′-dinitramino-3, 3′-bi(1, 2, 4-oxadiazole) (3, DNABO), a new heterocyclic energetic compound, was synthesized by the simple nitration of 5, 5′-diamino-3, 3′-bi(1, 2, 4-oxadiazole) (2 ) with 95% fuming nitric acid. Abstract : In order to develop high energy density materials, 5, 5′-dinitramino-3, 3′-bi(1, 2, 4-oxadiazole) (3, DNABO), a new heterocyclic energetic compound, was synthesized by the simple nitration of 5, 5′-diamino-3, 3′-bi(1, 2, 4-oxadiazole) (2 ) with 95% fuming nitric acid. By treating compound3 with two equivalents of energetic bases or their salts, a series of energetic salts4–10 based on nitrogen-rich cations were readily obtained. Among them, the hydroxylammonium salt (5 ) shows the best comprehensive properties (5 : d = 1.879 g cm −3 ; T d = 190 °C; P = 36.2 GPa; v D = 8916 m s −1 ). In addition, the guanidinium salt (7 ) possesses excellent thermal stability with an onset decomposition temperature of 317 °C.
