while at least part of acyl-containing derivative of hexaazaisowurtzitan (b) is dissolved in mixed solvent (a); (II) removal of at least part of the first solvent from composition system to precipitate crystals of acyl-containing derivative of hexaazaisowurtzitan (c); and (III) isolation of precipitated crystals from composition system. This compound is useful as a precursor of explosive addition exhibiting high exploitation properties (in part, hexanitro- -hexaazaisowurtzitan). EFFECT: high yield and purity, simplified procedure, decreased cost. 36 cl, 4 tbl, 27 ex"/>
