Abstract
A process is described for converting HMF to FDCA, comprising dissolving a quantity of HMF in water to form an aqueous solution including HMF, combining the aqueous solution including HMF with an oxygen source in the presence of a homogeneous metal salt catalyst, but in the substantial absence of any solvent for the HMF and the homogeneous metal salt catalyst other than water, and under conditions which are effective for oxidizing HMF in the presence of the catalyst to form FDCA, and then recovering an FDCA precipitate.
