Abstract: Disclosed is a process to produce a dry purified carboxylic acid product comprising furan-2,5-dicarboxylic acid (FDCA). The process comprises oxidizing at least one oxidizable compound to generate a crude carboxylic acid slurry comprising FDCA, removing impurities from a crude carboxylic acid slurry in a liquid displacement zone to form a low impurity slurry stream. The low impurity slurry stream is further treated in a secondary oxidation zone to produce a secondary oxidation slurry stream which is routed to a crystallization zone to form a crystallized slurry stream. The crystallized slurry stream is cooled in a cooling zone and the resulting cooled crystallized slurry stream is routed to a solid-liquid separation zone to generate a purified wet cake stream comprising FDCA that is dried in a drying zone to generate a dry carboxylic acid product stream comprising purified FDCA (pFDCA).

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 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).

Abstract: Disclosed is a process to produce a purified vapor comprising dialkyl-furan-2,5-dicarboxylate (DAFD). Furan-2,5-dicarboxylic acid (FDCA) and an alcohol in an esterification zone to generate a crude diester stream containing dialkyl furan dicarboxylate (DAFD), unreacted alcohol, 5-(alkoxycarbonyl)furan-2-carboxylic acid (ACFC), and alkyl furan-2-carboxylate (AFC). The crude diester stream is fed to a flash evaporation zone to produce a vapor alcohol composition and a first liquid DAFD rich composition. At least a portion of the remaining alcohol can be separated from the first liquid DAFD rich composition to produce a second alcohol vapor and a second liquid DAFD rich composition, followed by separating AFC from the second liquid DAFD rich composition to product an AFC vapor and a partially purified DAFD rich composition, followed by separating a portion of the DAFD from the partially purified DAFD rich composition to produce a purified DAFD vapor.
