Abstract:
Provided herein is a process for preparing furan-2,5-dicarboxylic acid. The process includes the following steps: (A-1) preparing a starting mixture comprising one, two or more carbohydrate compounds selected from the group consisting of: hexoses, oligosaccharides comprising hexose units, and polysaccharides including hexose units, and as a solvent or as a co-solvent for the carbohydrate compounds an amount of one or more carboxylic acid esters of a formula (II) and (A-2) subjecting the starting mixture to reaction conditions so that at least one of the one, two or more carbohydrate compounds reacts, and a fraction of the amount of one or more carboxylic acid esters of formula (II) is hydrolyzed, resulting in a mixture including 5-(hydroxymethyl)furfural and/or the one or more HMF esters of a formula (I), one or more carboxylic acids of a formula (III) and a remaining fraction of the amount of one or more carboxylic acid esters of formula (II).

Claim (Index 13):
The process according to  claim 1 , wherein at least 90% by weight of the total amount of said one or more carboxylic acids of formula (III) as obtained in step (A-2) is present in the mixture subjected to oxidation conditions in step (B-1), and/or wherein between steps (A-2) and (B-1): (i) there is no solvent change step, or (ii) no carboxylic acid of formula (III) is removed, and an additional amount of one, two, or more carboxylic acids of formula (III) is added.
