Method for preparing purified acid composition |
| abstract |
A process for preparing a purified acid composition comprising 2,5-furandicarboxylic acid (FDCA) comprising: a) A solution of the acid composition of the crude composition comprising 2,5-furan dicarboxylic acid (FDCA) and 2-formyl-furan-5-carboxylic acid (FFCA) ; b) a hydrogenation catalyst to hydrogenate the FFCA to the hydrogenation product so that the hydrogenation product contains a small amount of 2-methyl-furan-5-carboxylic acid (MFA) Contacting the acid composition solution with hydrogen in the presence of a catalyst; c) separating at least a portion of the FDCA from the hydrogenated solution by crystallization. |
