    摘要: The invention relates to a method for producing dinitro-diaza-alkanes and intermediate products hereto from alkylamines and esters. According to the inventive method, a dialkylester of a dicarboxylic acid is converted with an alkylamine in an aqueous medium into the corresponding dialkyldiamide of the dicarboxylic acid. The obtained dialkyldiamide is nitrated using common nitrating agents to form the corresponding dialkyldinitroamide of the dicarboxylic acid. The obtained dialkyldinitroamide is converted with methylamine and/or ethylamine in an aqueous medium into the corresponding alkyl nitramine and into dimethylamide and/or diethyldiamide of the dicarboxylic acid. The alkyl nitramine is isolated out therefrom and is condensed in a conventional manner to form dinitro-diaza-alkanes.
