Abstract

FIELD: fine chemical technology of organic substances. SUBSTANCE: product of NH-acid of azole series is extracted from aqueous solutions of rection mass by diluting reaction mass with water up to content of desired component of 30-60 g/l, setting up medium pH within the range indicated in the invention description, clarification of produced solutions with the aid of dusty microporous activated carbon and their subsequent passing through layer of granulated activated carbon of same type up to value of filling of adsorption space with desired component of 0.32-0.15 g/g. EFFECT: simplified technology, increased yield of desired product and extended field of application. 1 tbl
