Abstract:
A process for preparing a hexanitrohexaazaisowurtzitane represented by the following formula (VI):W N.sub.6 (VI)wherein N is a nitro group and W is a hexavalent hexaazaisowurtzitane residue, by nitrating with a nitrating agent any one of hexaazaisowurtzitane derivatives represented by the following general formulae (I), (III) and (IV):W A.sub.n N.sub.(6-n) (I)wherein n is an integer of 4 or 5, A is an acyl group having 1-10 carbon atoms with each acyl group being the same as or different from one or more of the others, N is a nitro group and W is a hexavalent hexaazaisowurtzitane residue,W A.sub.n NS.sub.(6-n) (III)wherein n is an integer of 4 or 5, A is an acyl group having 1-10 carbon atoms with each acyl group being the same as or different from one or more of the others, NS is a nitroso group and W is a hexavalent hexaazaisowurtzitane residue, andW A.sub.m H.sub.(6-m) (IV)wherein m is an integer of 4-6, A is an acyl group having 1-10 carbon atoms with each acyl group being the same as or different from one or more of the others, H is a hydrogen atom and W is a hexavalent hexaazaisowurtzitane residue.
