Abstract:
A process for producing furan dicarboxylic acid or an ester thereof from a feedstock comprising hydroxymethyl furfural (HMF) and humins is disclosed. Humins are a byproduct from reactions forming HMF from sugars and are typically removed from the HMF prior to any further processing. A humins-containing HMF feedstock is utilized to produce furan dicarboxylic acids and ester substantially free from humins.

Claim (Index 7):
A process comprising:\n i) oxidizing a feedstock comprising hydroxymethyl furfural and humins in a solvent to produce a mixture comprising crude humins-containing 2,5-furan dicarboxylic acid; ii) filtering the mixture under high temperature to obtain a filtrate comprising 2,5-furan dicarboxylic acid substantially free of humins, wherein the filtration temperature is sufficiently high to keep the 2,5-furan dicarboxylic acid soluble in the solvent; iii) esterifying the 2,5-furan dicarboxylic acid substantially free of humins with an alcohol to produce a crude ester of 2,5-furan dicarboxylic acid; and iv) purifying the crude ester of 2,5-furan dicarboxylic acid obtained in step iii) by distillation or sublimation to obtain a purified ester.
