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 1):
A process comprising:\n a) oxidizing a feedstock comprising hydroxymethyl furfural and humins to produce a mixture comprising crude humins-containing 2,5-furan dicarboxylic acid; b) separating the mixture to obtain a solid 2,5-furan dicarboxylic acid/humins composition; c) esterifying the solid 2,5-furan dicarboxylic acid/humins composition with an alcohol to produce a crude ester of 2,5-furan dicarboxylic acid; and d) purifying the crude ester of 2,5-furan dicarboxylic acid obtained in step c) by distillation or by sublimation to produce a purified ester of 2,5-furan dicarboxylic acid substantially free of humins.
