METHOD FOR PREPARING CARBONYL DERIVATIVE BY OXIDATION OF ALCOHOL BY NITROGEN-CONTAINING CATALYST

Title:

METHOD FOR PREPARING CARBONYL DERIVATIVE BY OXIDATION OF ALCOHOL BY NITROGEN-CONTAINING CATALYST

Document Type and Number:

WIPO Patent Application WO/2022/006690

Kind Code:

A1

Abstract:

A method for preparing a carbonyl derivative by oxidation of an alcohol by a nitrogen-containing catalyst, comprising the following steps: S1, mixing an organic matter having hydroxyl functional groups, trifluoroacetic acid, and an aqueous solution of a nitrogen-containing catalyst in an oxygen atmosphere at room temperature for reaction; S2, separating the trifluoroacetic acid by a distillation method; S3, mixing the remaining mixture with an aqueous solution of bisulfite, and then separating a target product by solvent extraction; and S4, separating the target product from the extraction solvent by a distillation method to obtain the target product. The method is low in production cost, simple in reaction process, good in economic efficiency, and wide in application prospect.
