PROCESS FOR PRODUCING 5-HYDROXYMETHYLFURFURAL USING METAL PHOSPHATES

Abstract: processes for synthesizing 5-hydroxymethylfurfural are described. the processes comprise contacting a feed comprising biomass-derived cellulose, or a sugar monomer or oligomer, or a mixture thereof with a catalyst comprising a metal phosphate. the metal phosphate may comprise hafnium phosphate, or zirconium phosphate, or combinations thereof. the catalyst has a ratio of bronsted acid sites to lewis acid sites greater than or equal to 0.27 and a total acid density less than or equal to 0.4.
