Abstract

A family of energetic salts based on 3,7-diamino-7H-[1,2,4]triazolo[4,3-b][1,2,4]triazol-2-ium were prepared by reaction of 3,7-diamino-7H-[1,2,4]triazolo[4,3-b][1,2,4]triazole (3) with corresponding energetic acids. The nitration product, 7-nitroimino-7H-[1,2,4]triazolo[4,3-b][1,2,4]triazole (4), was synthesized by using 100% nitric acid. The calculated detonation performance shows that compound 10, composed of 3,7-diamino-7H-[1,2,4]triazolo[4,3-b][1,2,4]triazol-2-ium and 3,3′-dinitramino-4,4′-azoxyfurazanate, has good density (1.830 g cm−3), high decomposition temperature (201 °C) and detonation performance (9077 m s−1, 34.4 GPa) as well as acceptable sensitivities (10 J, 240 N), which is superior to those of 1,3,5-trinitroperhydro-1,3,5-triazine (RDX).
