FIELD: chemistry.
SUBSTANCE: method for producing a hydroxylation catalyst for aromatic compounds with nitrogen oxide, which is an iron-containing zeolite of the MFI structure and/or MEL with a binder, modified with the ruthenium compounds in the amount of 0.01-5.0 wt % based on the metal, the soluble ruthenium compound is introduced in the step of forming the zeolite with the binder, or after moulding and calcining, or after moulding, calcining and thermocouple processing. The catalyst is regenerated at the temperature of 450-475°C in an inert gas medium containing 1 to 2 wt % of oxygen.
EFFECT: maximum activity and selectivity of the catalyst.
