FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to a method for preparing dinitrodiazaalkanes that can be used in producing gun powders used for warhead charges. Invention describes a method for preparing dinitrodiazaalkanes from alkylamines and esters in the following reactions: (1) dicarboxylic acid ester is subjected for interaction with alkylamine in an aqueous medium to form the corresponding dicarboxylic acid dialkyldiamide; (2) prepared dialkyldiamide is nitrated with usual nitrating agent to the corresponding dicarboxylic acid dialkyldinitroamide; (3) prepared dialkyldinitroamide is converted to the corresponding alkylnitroamine by mixing dialkyldinitroamide with methyl- and/or ethylamine in an aqueous medium and formed dimethyl- and/or diethylamide of dicarboxylic acid are separated and remaining substance is acidified and alkylnitroamine is extracted; (4) isolated alkylnitroamine is condensed to dinitrodiazaalkanes spontaneously by the known method. Invention provides the development of industrial method for preparing dinitrodiazaalkanes that is carried out easily and without enhanced consumptions and large risk.
EFFECT: improved preparing method.
