A process for preparing 5-(alkoxycarbonyl)furan-2-carboxylic acids (ACFC) by oxidizing various furcates in the presence of a catalyst containing cobalt, manganese, and bromine, and a solvent while simultaneously removing water vapor from the reaction chamber. The process can produce ACFC with high purity and low color, and in high yield.

The present invention relates to a method for the manufacture of stable FDCA precursors from saccharide derived starting materials. More specific the invention relates to the synthesis of FDCA precursors such as alkyl 5-(hydroxymethyl)furan-2-carboxylates or 5-(hydroxymethyl)furan-2-carboxylic acid in an expedient, practical and environmental benign manner from e.g. D-glucono-δ-lactone. These bio-based monomer building blocks hold great potential in the manufacture of polymer materials.

Disclosed herein is a very efficient method to make 5-(alkoxycarbonyl)furan-2-carboxylic acids (ACFC) from feedstocks comprised of furoates. When a feedstock comprised of methyl 5-methylfuran-2-carboxylate (MMFC) is used a product comprised of (5-(methoxycarbonyl)furan-2-carboxylic acid (MCFC) is obtained in high yield.
