Hexanitrohexaazaisowurtzitane remodification in three-component crystallization systems

详细

Processes of hexanitrohexaazaisowurtzitane remodification were studied at various temperatures for three crystallization systems based on acetone, ethyl acetate, and acetonitrile. The remodification conditions of the α- and β-forms into the required ε-modification and also the conditions in which the γ-modification is formed were found. The crystal habits of crystals of the ε-polymorphic modification of hexanitrohexaazaisowurtzitane, obtained in the crystallization systems under study, are described.
