METHOD FOR PRODUCTION OF 5-HYDROXYMETHYLFURFURAL

摘要

PURPOSE: A method for preparing 5-hydroxymethyl furfural(HMF) is provided to easily isolate and purify metal catalyst after HMF conversion. CONSTITUTION: A method for preparing 5-hydroxymethyl furfural comprises: a step of mixing fructose and irregular metal catalyst in an organic solvent; a step of heating the mixture and stirring. The irregular metal catalyst is denoted by chemical formula I and contains imidazole ligand of solid phase. The heating temperature during the reaction is 50-130°C.
