Abstract:The tetrahydrate of the tetrapotassium salt of octahydroimidazo- [4,5-d]imidazol-1,3,4,6-tetrasulfonic acid (TACOS-K), an new energetic material, was investigated in terms of its crystal structure, heat of combustion, thermal stability and decomposition kinetics. Its heat of combustion is -5487 ± 96 J g -1 from which a heat of formation of -3150 kJ mol -1 was estimated. It has been found that this compound has a hexagonal crystal space group with a density of 2.026 g mol -1 at 150 K. The organic anionic skelet… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
