Abstract: A purified acid composition including 2,5-furandicarboxylic acid is prepared by a process including a) providing an acid composition solution of a crude acid composition in a polar solvent, the crude acid composition including 2,5-furandicarboxylic acid (FDCA) and 2-formyl-furan-5-carboxylic acid (FFCA); b) contacting the acid composition solution with hydrogen in the presence of a hydrogenation catalyst to hydrogenate FFCA to hydrogenation products, such that the hydrogenation products contain a minor amount of 2-methyl-furan-5-carboxylic acid (MFA) or no MFA, yielding a hydrogenated solution; c) separating at least a portion of the FDCA from the hydrogenated solution by crystallization.

Abstract: Disclosed is a method for producing a polyethylene-2,5-furandicarboxylate (PEF) raw yarn including a spinning/drawing process wherein an undrawn yarn, obtained by melt-spinning of a PEF-containing resin composition, is continuously drawn into a PEF raw yarn without being recovered and the PEF raw yarn is taken up, wherein the ratio of a rate (T) of taking up the PEF raw yarn to a rate (E) of extrusion of the resin composition into filaments during the melt-spinning (T/E) is 700 to 2,000.

Abstract: 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.
