Abstract

The invention discloses a method for synthesizing cyclohexanol and cyclohexanone by electrochemically catalytically oxidizing cyclohexane and belonging to the technical field of organic electrochemical synthesis. The porous metal electrocatalytic membrane loaded with metal oxide is used as the anode, and the auxiliary electrode is used as the cathode to form an electrocatalytic membrane reactor; the reaction raw material solution is a mixed aqueous solution of cyclohexane, organic solvent and electrolyte, under certain operating voltage and current density conditions Under the conditions, cyclohexane is catalyzed and oxidized to the products cyclohexanol and cyclohexanone on the surface of the membrane and in the pores by the metal oxide supported on the membrane. It is pumped to the permeate side to achieve real-time online separation or transfer, and then the membrane permeate is separated and purified to finally obtain the products cyclohexanol and cyclohexanone. Compared with traditional techniques, the invention has the advantages of high efficiency, greenness, high selectivity, simple operation, etc., is suitable for industrial implementation, and has broad application prospects.

Description

technical field

[0001] The invention belongs to the technical field of organic electrochemical synthesis, in particular to a method for synthesizing cyclohexanol and cyclohexanone by electrochemically catalyzing cyclohexane oxidation. Background technique

[0002] Cyclohexanol and cyclohexanone are extremely important chemical raw materials, and are necessary intermediates for the production of caprolactam and adipic acid. The preparation of cyclohexanol / ketone by liquid-phase cyclohexane oxidation is an industrially very important and commercially valuable chemical synthesis method. At present, the methods for synthesizing and preparing cyclohexanol / ketone at home and abroad are mainly cyclohexane oxidation. The cyclohexane oxidation method is divided into non-catalytic oxidation method and catalytic oxidation method, and the catalytic oxidation method is divided into photocatalytic oxidation method, boric acid catalyst oxidation method, cobalt salt catalytic oxidation met...
