| titleOfInvention | Method for producing purified dialkyl-furan-2,5-dicarboxylate by physical separation and solid liquid separation |
| abstract | A process to produce a purified dimethyl-furan-2,5-dicarboxylate (DMFD) by feeding furan dicarboxylic acid and methanol to an esterification zone to generate, in the absence of an esterification catalyst, a crude diester composition, and purifying the crude diester composition with a physical separation process followed by crystallization, solid liquid separation, and optionally drying to produce a purified DMFD composition. A portion of the stream generated by solid liquid separation can be dissolved and subjected to crystallization and solid liquid separation repeatedly. The process is useful to produce a purified DMFD composition having a low b*, at least 98 wt.% DAFD solids, and a low concentration of 5-(methoxycarbonyl)furan-2-carboxylic acid (MCFC) and methyl 5-formylfuran-2-carboxylate (MFFC). |
