METHOD FOR PREPARING 2,5-FURANDICARBOXYLIC ACID BY CATALYTIC OXIDATION OF 2,5-DIFORMYLFURAN

Title:

METHOD FOR PREPARING 2,5-FURANDICARBOXYLIC ACID BY CATALYTIC OXIDATION OF 2,5-DIFORMYLFURAN

Document Type and Number:

WIPO Patent Application WO/2018/082234

Kind Code:

A1

Abstract:

A method for preparing 2,5-Furandicarboxylic acid by catalytic oxidation of 2,5-Diformylfuran. The method uses hyperoxide as an oxygen source; the 2,5-Diformylfuran is oxidized to be the 2,5-Furandicarboxylic acid under the effect of a sulfuric acid based catalyst. The method has high oxidation efficiency and high yield of product, is economical and environmentally friendly by using hyperoxide the oxygen source, and has considerable promise for application for the easily separated product and catalyst and simple after-treatment.
