Abstract
Hydroxymethylfurfural (HMF) is derived from C6 sugars and is a versatile platform chemical with the potential to replace a range of conventional building blocks. It has been found that the remove of certain components such as oxygenated contaminants from C6 sugars can significantly improve the yields of HMF. The oxygenated contaminants may be removed by ion exchange resins, adsorbents, solvent extraction and pH adjustment via addition of base.

A process of synthesizing hydroxymethylfurfural comprising removing, converting or neutralizing oxygen containing contaminants from a feed comprising biomass-derived cellulose, or a sugar monomer or oligomer, or a mixture thereof to produce a purified feed and reacting said purified feed under reaction conditions with a catalyst to produce said hydroxymethylfurfural.
A process of synthesizing hydroxymethylfurfural comprising removing, converting or neutralizing oxygenates from a feed comprising biomass-derived cellulose, or a sugar monomer or oligomer, or a mixture thereof to produce a purified feed and reacting said purified feed under reaction conditions with a catalyst to produce said hydroxymethylfurfural.
A process of synthesizing hydroxymethylfurfural comprising removing, converting or neutralizing acids from a feed comprising biomass-derived cellulose, or a sugar monomer or oligomer, or a mixture thereof to produce a purified feed and reacting said purified feed under reaction conditions with a catalyst to produce said hydroxymethylfurfural.
