    • A method of synthesis of dinitro-diaza-alkanes and intermediate products thereto from alkylamines and esters, whereby a dialkyl ester of a dicarboxylic acid is reacted with an alkylamine in an aqueous medium to form the corresponding dialkyldiamide of the dicarboxylic acid; the resulting dialkyldiamide is nitrated by means of conventional nitration agents to form the corresponding dialkyldinitroamide of the dicarboxylic acid and; the resulting dialkyldinitroamide is reacted with methylamine and/or ethylamine in an aquous medium to yield a corresponding alkylnitroamine and the dimethyldiamide and/or diethyldiamide of the dicarboxylic acid, and the alkylnitroamine is isolated from that, and the isolated alkylnitroamine is condensed in a known manner to form the dinitro-diaza-alkanes.

    • A process for the production of a high energy material involves reacting, in an inert organic solvent, a heterocyclic compound selected from oxirane, aziridine, oxetane or azetidine with a nitrogen oxide selected from dinitrogen tetroxide (N.sub.2 O.sub.4) and dinitrogen pentoxide (N.sub.2 O.sub.5) and, when the nitrogen oxide is N.sub.2 O.sub.4, oxidizing the O- or N- nitroso substituent or substituents in the product obtained to O- or N- nitro substituent or substituents. The heterocyclic compounds may be substituents or unsubstituted. In the former case the preferred substituents groups are halogen, alkyl, alkenyl, nitro and epoxy (as in epoxidized polybutadiene). The solvent is preferably a chlorinated alkane.Novel nitrated derivatives of polybutadiene, in which between 1% and 25% of the carbon atoms in the polymer are substituted by nitrate (ONO.sub.2), are also provided. These novel materials are liquid rubbers when the polybutadiene starting material has a molecular weight between 2000 and 10000.
    • 用于生产高能材料的方法包括在惰性有机溶剂中使选自环氧乙烷,氮丙啶,氧杂环丁烷或氮杂环丁烷的杂环化合物与选自四氧化二氮(N 2 O 4)和五氧化二氮(N 2 O 5)的氮氧化物反应, 当氮氧化物是N 2 O 4时,将获得的产物中的O-或N-亚硝基取代基或取代基氧化成O-或N-硝基取代基。 杂环化合物可以是取代基或未取代的。 在前一种情况下,优选的取代基是卤素,烷基,烯基,硝基和环氧基(如在环氧化的聚丁二烯中)。 溶剂优选为氯化烷烃。 还提供了聚合物中1%至25%的碳原子被硝酸(ONO 2)取代的聚丁二烯的新型硝化衍生物。 当聚丁二烯起始材料的分子量在2000和10000之间时,这些新型材料是液体橡胶。
