Abstract
A process is described for converting hydroxymethylfurfural to furanic products inclusive of 2,5-furandicarboxylic acid, comprising combining a quantity of hydroxymethylfurfural with water to provide an aqueous solution containing at least about five percent by weight of hydroxymethylfurfural, and combining the aqueous solution with an oxygen source in the presence of a heterogeneous ruthenium-based catalyst and under conditions which are effective for oxidizing hydroxymethylfurfural to furanic oxidation products inclusive of 2,5-furandicarboxylic acid, but in the substantial absence of any solvent for either hydroxymethylfurfural or 2,5-furandicarboxylic acid other than water.
