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.

Acid chloride derivatives of 5-(chloromethyl)furan-2-carboxylic acid and furan-2,5-dicarboxylic acid (FDCA) can be produced in high yield by treatment of the precursor aldehydes 5-(chloromethyl)furfural (CMF) and 2,5-diformylfuran (DFF) with tert-butyl hypochlorite, which is inexpensively prepared from commercial bleach and tert-butanol. 5-(Chloromethyl)furan-2-carbonyl chloride (CMFCC) and furan-2,5-dicarbonyl chloride (FDCC) are highly useful intermediates for the production of furoate ester biofuels and polymers of FDCA.

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.
