METHOD FOR BROMINATION OF XYLENES INTO RING Russian patent published in 2016 - IPC C07C17/12 C07C25/125

Abstract RU 2601752 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing xylene monobromides by oxidation bromination of xylenes. Method is characterized by that the bromine atom donor used is liquid bromine or an aqueous solution of hydrobromic acid, the oxidant used is an alkali metal bromate in an amount sufficient to provide a neutral reaction mixture during the bromination.

EFFECT: proposed method is easily implemented in industrial conditions, enables to obtain monobromoxylenes with high outputs, herewith a minimum amount of wastes is created.
