Abstract:
Provided herein is a process for preparing a mixture including 5-(hydroxy-methyl)furfural (HMF) and one or more HMF esters of formula (I), the process including the following steps: (A-1) preparing or providing a starting mixture which includes one, two or more carbohydrate compounds and as the solvent or as a co-solvent for the carbohydrate compounds an amount of one or more carboxylic acid esters of formula (II); (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, so that a mixture results that includes 5-(hydroxy-methyl)furfural and/or the one or more HMF esters of formula (I), one or more carboxylic acids of 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 a mixture comprising 5-(hydroxymethyl)furfural (HMF) and one or more HMF esters of formula (I), wherein in 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, the process comprising the following steps: (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, and \n as the solvent or as a co-solvent for said carbohydrate compounds an amount of \n one or more carboxylic acid esters of formula (II) \n wherein in each of said carboxylic acid esters of formula (II)\n R1 is the same as defined for formula (I) above 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\n at least one of said one, two or more carbohydrate compounds reacts, and \n a fraction of said amount of one or more carboxylic acid esters of formula (II) is hydrolyzed, \n such that a mixture results comprising\n 5-(hydroxymethyl)furfural and/or said one or more HMF esters of formula (I), \n one or more carboxylic acids of formula (III) \n \n wherein R1 is the same as defined for formula (I) above, one or more alcohols R2-OH, wherein R2 is the same as defined for formula (II) above, and a remaining fraction of said amount of one or more carboxylic acid esters of formula (II), wherein the starting mixture prepared or provided in step (A-1) comprises a total amount of carboxylic acid esters of formula (II) of at least 50 wt.-%, based on the total weight of the starting mixture.
