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.
生产高能硝酸酯的过程涉及在惰性有机溶剂中,将来自环氧烷、环氧乙烷、N-取代环氧丙烷和N-取代环氧丁烷的杂环化合物与N.sub.2 O.sub.4或N.sub.2 O.sub.5反应,当该化合物与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。杂环化合物上剩余的环碳原子可以是取代的或未取代的。化合物上的C和/或N环原子的首选取代基团包括烷基、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,其中聚合物中1%至25%的碳原子被邻位硝酸酯(--ONO.sub.2)基取代。
