    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.
