PROBLEM TO BE SOLVED: To provide a method of easily and economically producing a highly pure 5-hydroxymethylfurfural oxide from sugar raw material.SOLUTION: A method of producing a 5-hydroxymethylfurfural oxide includes following processes a-d. In the process a: sugar raw material is subjected to a dehydration reaction in the presence of a reaction solvent to produce 5-hydroxymethylfurfural (HMF) in the reaction solvent, and the reaction solvent including HMF is obtained. In the process a: sugar raw material is subjected to a dehydration reaction in the presence of a reaction solvent to produce 5-hydroxymethylfurfural in the reaction solvent, and the reaction solvent including HMF is obtained. In the process b: HMF is extracted into a hydrophobic solvent from the reaction solvent including HMF obtained in the process a, and the hydrophobic solvent including HMF is obtained. In the process c: HMF is extracted into water from the hydrophobic solvent including HMF obtained in the process b, and an aqueous solution including HMF is obtained. In the process d: HMF obtained in the process c is oxidized. |
