METHOD FOR PREPARING ORGANIC AZIDES Russian patent published in 2004 - IPC

Abstract RU 2241714 C2

FIELD: organic chemistry, chemical technology.

SUBSTANCE: method for preparing azide derivative of organic compound involves addition of azide function to organic compound by reaction of epoxy derivative of organic compound with alkaline metal azide salt in solvent. Before and/or during reaction (C₂-C₄)-carboxylic acid (C₁-C₆)-alkyl ester is added reaction mixture at boiling point above the reaction temperature in the about equimolar amount with respect to epoxy derivative. Epoxy derivative of organic compound is taken among styrene oxide, 2,3-epoxybutane, indene oxide and carbohydrate epoxy derivative. The reaction temperature is between 60^oC and 120^oC. Method provides reducing the amount of by-side products, diminishing corrosion of reactor enamel coating.

EFFECT: improved preparing method.
