A New Method for Synthesis of 5-Hydroxymethylfurfural(5-HMF)and Its Derivatives from Methyl 2,3-O-Sulfonyl-α-D-glucoside
Based on the dilemma of industrial application of preparing 5-hydroxymethylfuraldehyde(5-HMF)from biomass,a new method for preparing 5-HMF is obtained in this study.In the preparation method,anhydrous D-glucose obtained from the acid hydrolysis of cellulose,the most important bio-mass,is used as the starting material,and 5-HMF is finally obtained through Methylglycosylation,iso-propylation,cyclic sulfate esterification and high-temperature dehydration.In this method,the inter-mediate obtained in each step does not require additional purification process,and the reagents in-volved in the preparation are easy to obtain and cheap,so the method has excellent industrial applica-tion prospects.
