    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 selected from the following group: 5-(hydroxymethyl)furfural (5-HMF), 5-HMF esters (5-R(CO)OCH2-furfural where R=alkyl, cycloalkyl and aryl), 5-HMF ethers (5-R′OCH2-furfural, where R′=alkyl, cycloalkyl and aryl), 5-alkyl furfurals (5-R″-furfural, where R″=alkyl, cycloalkyl and aryl), mixed feed-stocks of 5-HMF and 5-HMF esters and mixed feed-stocks of 5-HMF and 5-HMF ethers and mixed feed-stocks of 5-HMF and 5-alkyl furfurals 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).
