Abstract
The present invention relates to a method for producing a furan-based compound using an ion exchange resin in the presence of an organic solvent. In the method for producing a furan-based compound according to the present invention, a furan-based compound is made from an aldose-type hexose compound in the presence of an organic solvent by using an anion exchange resin and a cation exchange resin. Thus, the aldose-type hexose compound obtained from biomass by simultaneously or consecutively using the anion/cation exchange resins as catalysts can be made into 5-hydroxymethyl-2-furfural (HMF) or alkyl ether derivatives thereof such as 5-alkoxymethyl-2-furfural (AMF) without using an expensive reagent. Also, since the selection of an organic solvent is not limitative and a heterogeneous catalyst can be used, separation and purification is easy and chemically stable AMF can be directly obtained. Further, the conversion efficiency of the aldose-type hexose compound is excellent, and the hexose compound can be used at a high concentration.
