Abstract

The invention discloses a method for preparing 2,5-diformyl furan through selective oxidation of 5-hydroxymethylfurfural, which comprises the steps of reacting 5-hydroxymethylfurfural serving as a raw material, a four-component molybdenum-based compound Co9Fe3BiMo12O51 serving as a catalyst and oxygen serving as an oxidant in dimethyl sulfoxide under normal pressure and heating conditions for a certain time to obtain 2,5-diformyl furan, wherein the catalyst can be repeatedly used after being centrifugally separated, washed and dried. The conversion rate of the raw material 5-hydroxymethylfurfural is high, the yield of the product 2,5-diformyl furan is high, and the catalyst Co9Fe3BiMo12O51 can be repeatedly used.

Description

technical field [0001] The invention relates to a method for preparing 2,5-diformyl furan by selective oxidation of 5-hydroxymethylfurfural. Background technique [0002] Using biomass as the initial raw material to prepare various chemicals such as bulk chemicals, specialty chemicals, intermediates, and fine chemicals is an important way to utilize biomass resources. To complete the utilization process of biomass, generally speaking, the biomass should first be converted into platform compounds through chemical depolymerization or enzymatic catalysis, and then the platform compounds should be converted into corresponding chemicals through various chemical processes. 5-Hydroxymethylfurfural can be produced by acid-catalyzed dehydration of carbohydrates such as cellulose, glucose and fructose, and is a very important biomass-based platform compound. 2,5-diformylfuran is one of the important oxidation products of 5-hydroxymethylfurfural. It is widely used, mainly as antifunga...
