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 1):
A process for preparing furan-2,5-dicarboxylic acid, the process comprising the following steps:\n (A-1) preparing or providing a starting mixture comprising:\n one, two, or more carbohydrate compounds selected from the group consisting of: hexoses, oligosaccharides comprising hexose units, and polysaccharides comprising hexose units, \n and as a solvent or as a co-solvent for said carbohydrate compounds an amount of one or more carboxylic acid esters of a formula (II) \n wherein for each of said carboxylic acid esters of formula (II):\n R1 is hydrogen or a substituted or unsubstituted, branched or linear, saturated or unsaturated or aromatic hydrocarbon radical having a total number of 21 carbon atoms or less, and \n R2 is a substituted or unsubstituted, branched or linear or cyclic, aliphatic hydrocarbon radical having a total number of 10 carbon atoms or less, \n (A-2) subjecting said starting mixture to reaction conditions such that at least one of said one, two, or more carbohydrate compounds reacts, and a fraction of said amount of one or more carboxylic acid esters of formula (II) is hydrolyzed, such that a mixture results comprising:\n 5-(hydroxymethyl)furfural and/or one or more HMF esters of formula (I) \n wherein for each of said HMF esters of formula (I), independently of each other, R1 is (i) hydrogen or (ii) a substituted or unsubstituted, branched or linear, saturated or unsaturated or aromatic hydrocarbon radical having a total number of 21 carbon atoms or less,\n one or more carboxylic acids of a formula (III) \n wherein R1 is the same as defined for formula (I) above,\n one or more alcohols R2-OH, wherein R2 is the same as defined for formula (II) above, and \n a remaining fraction of said amount of one or more carboxylic acid esters of formula (II), \n (B-1) subjecting\n said mixture resulting in step (A-2) or \n a mixture comprising 5-(hydroxymethyl)furfural and/or one or more HMF esters of formula (I) obtained from said mixture resulting in step (A-2) by additional treatment steps \n to oxidation conditions such that a product mixture results comprising furan-2,5-dicarboxylic acid and one or more carboxylic acids of formula (III).
