    摘要： A purified acid composition including 2,5-furandicarboxylic acid is prepared in a process, including oxidizing a feedstock containing 5-alkoxymethylfurfural to an oxidation product including 2,5-furandicarboxylic acid (FDCA) and 2-formyl-furan-5-carboxylic acid (FFCA), and esters of FDCA and, optionally, esters of FFCA; hydrolyzing the at least part of the oxidation product in the presence of water, thereby hydrolyzing at least esters of FDCA and, optionally, esters of FFCA to obtain an aqueous solution of an acid composition including FDCA, FFCA and ester of FDCA in an amount below the amount of ester of FDCA in the solution of the oxidation product; contacting at least part of the solution of the acid composition with hydrogen in the presence of a hydrogenation catalyst to hydrogenate FFCA to hydrogenation products, yielding a hydrogenated solution; and separating at least a portion of the FDCA from at least part of the hydrogenated solution by crystallization.

    摘要： where R represents hydrogen, an alkyl group or an acyl group, is prepared in a process, which process includes reacting a fructose-and/or glucose-containing starting material with a liquid hydroxyl group-containing compound of formula R—OH in the presence of an acid catalyst at a reaction temperature in the range of 150 to 300° C. to produce a primary acid reaction mixture including the furfural derivative of chemical formula (1); separating part of the liquid hydroxyl group-containing compound from the primary acid reaction mixture to yield a secondary acid reaction mixture; neutralizing the secondary acid reaction mixture to a pH-value of at least 3 to obtain a neutralized reaction mixture; and purifying the neutralized reaction mixture to recover the furfural derivative of chemical formula (1).

    摘要： Dialkyl esters of 2,5-furandicarboxylic acid are prepared from a 2,5-furandicarboxylic acid-containing starting material in a process, which includes: contacting a vaporous stream of an alkanol countercurrently with the at least partially liquid starting material having the 2,5-furandicarboxylic acid, in a reaction zone to conduct an esterification reaction to yield the dialkyl ester of 2,5-furandicarboxylic acid and water; withdrawing a reaction vapor comprising the alkanol and water from the reaction zone; and discharging a liquid phase having at least the dialkyl ester of 2,5-furandicarboxylic acid, from the bottom part of the reaction zone, to obtain the dialkyl ester of 2,5-furandicarboxylic acid.

    摘要： Dialkyil esters of 2,5-furandicarboxylic acid are prepared in a process including: contacting an acid starting composition having 2,5-furandicarboxylic acid with an excess of alkanol to form an esterification product having the dialkyil ester of 2,5-furan dicarboxylic acid, water and unreacted alkanol; separating at least part of the unreacted alkanol and water from the esterification product to yield a solid crude product composition having the dialkyil ester of 2,5-furandicarboxylic acid; and subjecting at least part of the solid crude product composition to an evaporation step, where the dialkyil ester of 2,5-furandicarboxylic acid is evaporated and subsequently condensed to yield purified dialkyil ester of 2,5-furandicarboxylic acid.
