Abstract

The invention discloses a method for preparing cyclohexanol and cyclohexanone by virtue of electrochemically catalytic oxidation of cyclohexane in the technical field of organic electrochemical synthesis. The method comprises the following steps: forming an electrocatalytic membrane reactor by taking a metal oxide loaded porous metal electrocatalytic membrane as an anode and an auxiliary electrode as a cathode; with a mixed water solution of cyclohexane, an organic solvent and electrolyte as a reaction raw material solution, catalytically oxidizing cyclohexane on the surface of the membrane and in a hole by using metal oxide loaded on the membrane to form products, namely cyclohexanol and cyclohexanone under a certain working voltage and current density condition; meanwhile, sucking the products to a permeation side under a certain membrane permeation flux condition by means of negative pressure generated by a peristaltic pump to realize real-time online separation or transfer; then, separating and purifying a membrane permeation solution to finally obtain the products, namely cyclohexanol and cyclohexanone. Compared with the traditional process, the method has the advantages of high efficiency, environment friendliness, high selectivity, simplicity in operation and the like, is suitable for industrial implementation and has wide application prospect.

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...
