Title:
METHOD FOR SEPARATING 5-HYDROXYMETHYL-2-FURFURAL AND DIMETHYL SULFOXIDE IN PREPARATION PROCESS FOR 5-HYDROXYMETHYL-2-FURFURAL
Document Type and Number:
WIPO Patent Application WO/2019/039705
Kind Code:
A1
Abstract:
The present invention relates to a method for separating 5-hydroxymethyl-2-furfural (HMF) and dimethyl sulfoxide (DMSO), the method comprising the steps of: (a) preparing a mixture solution comprising HMF and DMSO; and (b) mixing an organic solvent and water with the mixture solution to prepare a layer separation solution in which an aqueous layer comprising the DMSO and an organic layer comprising the HMF are layer-separated, wherein the organic solvent comprises a first organic solvent comprising an aprotic nonpolar organic solvent and a second organic solvent comprising an aprotic polar organic solvent. According to the present invention, a dimethyl sulfoxide solvent and 5-hydroxymethyl-2-furfural can be effectively separated after the termination of a preparation reaction for 5-hydroxymethyl-2-furfural using dimethyl sulfoxide solvent.
