Patent ID: 8426583

Claim:
A process for preparing hexanitrohexaazaisowurtzitane comprising: dissolving hexa(1-propenyl)hexaazaisowurtzitane in acetone to form a first composition; forming singlet oxygen in the presence of said first composition; allowing contact of singlet oxygen and said hexa(1-propenyl)hexaazaisowurtzitane, at a predetermined temperature, to form a second composition including reaction products of hexa(1-propenyl)hexaazaisowurtzitane oxygenation; removing the acetone from said second composition to form a third composition including reaction products of hexa(1-propenyl)hexaazaisowurtzitane oxygenation; adding nitric acid to said third composition to form a fourth composition; refluxing said fourth composition under nitrogen in the presence of a strong Brønsted acid catalyst suitable for catalyzing nitrolysis of said reaction products of hexa(1-propenyl)hexaazaisowurtzitane oxygenation to form a fifth composition containing hexanitrohexaazaisowurtzitane; and, extracting hexanitrohexaazaisowurtzitane from said fifth composition.
