| titleOfInvention | Method for purifying a tetraacylhexaazaisowurtzitane and method for producing an acyl grupu-containing hexaazaisowurtzitane derivative |
| abstract | Disclosed is a method for producing an acyl group-containing hexaazaisowurtzitane derivative represented by the following formula (1), WAnH(6-n), wherein n represents an integer of 4 or 6, each A independently represents an acyl group having 1 to 10 carbon atoms, H represents a hydrogen atom, and W represents a hexavalent hexaazaisowurtzitane residue represented by the following formula (2): which comprises: providing a composition system comprising a mixed solvent of a first solvent and a second solvent respectively having high and low dissolving abilities for the desired compound, wherein the mixed solvent has the desired compound dissolvent therein; and removing the first solvent having a high dissolving ability from the composition system to thereby deposit crystals of the desired compound. The desired compound, which is useful as a precursor of high performance explosive additive, i.e., hexanitrohexaazaisowurtzitane, can be easily produced in high purity form in high yield and at low cost. |
