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 N.sub.2 O.sub.4 or N.sub.2 O.sub.5, and when the compound is reacted with N.sub.2 O.sub.4, 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 (--ONO.sub.2) groups.
一种生产高能硝酸酯的方法,包括在惰性有机溶剂中反应杂环化合物,所述杂环化合物选自环氧烷,环氧乙烷,N-取代环氧丙烷和N-取代环氧戊烷,与N.sub.2 O.sub.4或N.sub.2 O.sub.5反应,当化合物与N.sub.2 O.sub.4反应时,将产物中的O-或N-硝酸酯取代基氧化为O-或N-硝酸酯取代基。杂环化合物上的其余环碳原子可以是取代或未取代的。化合物上C和/或N环原子的首选取代基包括烷基,氰基烷基,卤代烷基,硝基烷基和取代芳基。还提供了几种新型硝酸酯,包括聚丁二烯的硝化衍生物,在该聚合物中,1%至25%的碳原子被邻位硝酸酯(-ONO.sub.2)基取代。
