Process for forming a dinitramide salt or acid by reaction of a salt or free acid of an N(alkoxycarbonyl)N-nitroamide with a nitronium-containing compound followed by reaction of the intermediate product respectively with a base or alcohol |
摘要 |
A method is disclosed for forming an ionically bonded dinitramide salt or acid useful as a stable oxidizer for solid fuel rocket propellant or explosive formulations is disclosed. The dinitramide salt is formed by the reaction of an N(alkoxycarbonyl)N-nitroamide and a nitronium-containing compound, at a temperature of from about +60 DEG C. to about -120 DEG C., followed by contacting the reaction mass with a base to form the dinitramide salt, or an alcohol to form the corresponding dinitramidic acid. The N(alkoxycarbonyl)N-nitroamide may be formed by first mixing the corresponding alkylcarbamate with an anhydride of one or more 1-20 carbon organic acids, then adding nitric acid to the reaction mixture. If the salt of the N(alkoxycarbonyl)N-nitroamide is to be formed, a base is then added until the pH reaches about 7-10. The nitronium-containing reactant may be a covalently bonded compound containing a NO2- group; a nitryl halide; or a nitronium salt having the formula (NO2+)qX-q, where X is the anion of the nitronium salt and q=1-2.
