| titleOfInvention | process for preparing a purified acid composition. |
| abstract | A purified acid composition comprising 2,5-furancarboxylic acid is prepared in a process comprising (i) oxidizing a 5-alkoxymethylfurfural raw material into an oxidation product comprising 2,5-furandicarboxylic acid (fdca) and 2- formyl furan-5-carboxylic acid (fca) and fca esters and, optionally, fca esters; (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 fdca esters and optionally ffca esters; (iii) hydrolyzing at least a portion of the oxidation product in the presence of water, thereby hydrolyzing at least fdca esters and optionally ffca esters to obtain an aqueous solution of an acidic composition comprising fdca, ffca and fdca ester. in an amount below the amount of fdca ester in the oxidation product solution; (iv) contacting at least a portion of the acid composition solution obtained in step (iii) with hydrogen in the presence of a hydrogenation catalyst to hydrogenate the hydrogenation products to produce a hydrogenated solution; and (v) separating at least a portion of the drug from at least part of the hydrogenated solution by crystallization. |
