| titleOfInvention | Method for purifying crude 2,5-furandicarboxylic acid composition |
| abstract | A method for purifying a crude 2,5-furandicarboxylic acid composition including 2,5-furandicarboxylic acid and 5-formylfuran-2-carboxylic acid is disclosed. The method includes the steps of: (a) subjecting the crude 2,5-furandicarboxylic acid composition to complete dissolution in a solvent solution to obtain a mixture, the solvent solution including an organic solvent and water; (b) subjecting 5-formylfuran-2-carboxylic acid in the mixture to an addition reaction with sodium hydrogen sulfite to obtain an addition product; and (c) subjecting 2,5-furandicarboxylic acid to precipitation after step (b) to obtain purified 2,5-furandicarboxylic acid. |
