FIELD: chemistry.
SUBSTANCE: invention relates to chemical industry. Alkyl nitrites from apparatus for production thereof are bubbled into an aqueous-alkali treatment apparatus and then into an apparatus for producing azides of alkali and alkali-earth metals, where they react with corresponding oxides or hydroxides of alkali or alkali-earth metals in a mixture with hydrazine. The alkyl nitrite after alkali treatment from spraying sulphuric acid, nitrogen and carbon oxides is used in gaseous form. The obtained product is cooled, filtered, washed and dried.
EFFECT: high purity of 98-99% and output of 85-95% with low power and time consumption.
