METHOD FOR RECOVERING FURFURAL-PRODUCING CATALYST, FURFURAL-PRODUCING CATALYST AND METHOD FOR PRODUCING FURFURAL USING THE FURFURAL-PRODUCING CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a method for recovering a furfural-producing catalyst and a method for producing furfural capable of easily removing water-soluble impurities to recover a catalyst and efficiently producing furfural by maintaining a high yield even when the recovered catalyst is used.SOLUTION: There are provided: a method for recovering a furfural-producing catalyst which comprises a step of producing furfural from sugar in a reaction solution containing a catalyst; and a method for recovering the furfural-producing catalyst which comprises a step of recovering the catalyst from the reaction solution by extraction using an organic solvent.SELECTED DRAWING: None
