A process for the production of a high energy nitrate ester involves reacting, in an inert organic solvent, a heterocyclic compound, selected from oxiranes, oxetanes, N-substituted aziridines and N-substituted azetidines, with either N2O4 or N2O5, and when the compound is reacted with N2O4, oxidizin
A process for the production of a high energy nitrate ester involves reacting, in an inert organic solvent, a heterocyclic compound, selected from oxiranes, oxetanes, N-substituted aziridines and N-substituted azetidines, with either N2O4 or N2O5, and when the compound is reacted with N2O4, oxidizing the O- or N-nitrate substituents or substituent in the product to O- or N-nitrate substituent or substituents. The remaining ring carbon atoms on the heterocyclic compound may be substituted or unsubstituted. Preferred substituent groups for the C and/or N ring atoms on the compound include alkyl, cyanoalkyl, haloalkyl, nitroalkyl, and substituted aryl. Several novel nitrate ester are also provided, including nitrated derivatives of polybutadiene, in which between 1% and 25% of the carbon atoms in the polymer are substituted by vicinal nitrate ester (-ONO2) groups.

A process for the production of a high energy material comprising the following steps: (a) reacting a heterocyclic strained ring compound, selected from the group consisting of oxiranes, oxetanes, aziridines and azetidines, with a nitrogen oxide selected from the group consisting of dinitrogen tetro
A process for the production of a high energy material comprising the following steps: (a) reacting a heterocyclic strained ring compound, selected from the group consisting of oxiranes, oxetanes, aziridines and azetidines, with a nitrogen oxide selected from the group consisting of dinitrogen tetroxide (N2O4) and dinitrogen pentoxide (N2O5) to open said heterocyclic strained ring and afford, when the nitrogen oxide is N2O4, a product A containing nitrato (-ONO2) and nitrito (-ONO) substituents or a product B containing nitrato and N-nitroso (>NNO) substituents, and afford, when the nitrogen oxide is N2O5, a product C containing nitrato substituents or a product D containing nitrato and N-nitro (>NNO2) substituents; (b) when the nitrogen oxide is N2O4, oxidising with ozone product A to product C or product B to product D; and (c) isolating product C or product D.
