| titleOfInvention | Process for the preparation of a purified acid composition |
| abstract | A purified acid composition comprising 2,5-furandicarboxylic acid is prepared in a process, comprising (i) oxidizing a feedstock containing 5-alkoxymethylfurfural to an oxidation product comprising 2,5-furandicarboxylic acid (FDCA) and 2-formyl-furan-5-carboxylic acid (FFCA), and esters of FDCA and, optionally, esters of FFCA; (ii) optionally, dissolving at least part of the oxidation product in a polar solvent to obtain a solution of the oxidation product, comprising FDCA, FFCA and esters of FDCA and, optionally, esters of FFCA; (iii) 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 comprising FDCA, FFCA and ester of FDCA in an amount below the amount of ester of FDCA in the solution of the oxidation product; (iv) contacting at least part of the solution of the acid composition obtained in step (iii) with hydrogen in the presence of a hydrogenation catalyst to hydrogenate FFCA to hydrogenation products, yielding a hydrogenated solution; and (v) separating at least a portion of the FDCA from at least part of the hydrogenated solution by crystallization. |
