    Abstract: The process of the present invention provides a method of obtaining a high yield of water or acid soluble nitrate esters without the use of organic solvents in the nitration reaction or the production of unstable products or by-products. The process involves the nitration of an organic hydroxy-containing compound with a suitable nitrating agent such as nitric acid in the absence of organic solvents in the nitration reaction. The reaction mixture is neutralized, causing the nitrate esters to precipitate or separate from the neutralized nitrate solution. The nitrate ester is then recovered, and any dissolved nitrate salts can be removed therefrom by gentle washing with water or a dilute halide solution. As provided by the process of the present invention, no organic solvents are used in the nitration reaction and average yields range from about 80% to about 95%.

    Abstract: 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.

    Abstract: Organic nitrogen compounds are formed in the vapor phase by organic radical formation by reaction of an organic compound, suitably an alkane, with hydroxyl radicals derived from the reaction between hydrogen peroxide and nitrogen dioxide and the nitration of the organic radicals, suitably with nitrogen dioxide. The process is conducted using a molecular oxygen additive which directs the reaction towards the formation of the nitrate corresponding to the organic compound which may predominate in the organic reaction products.
