    Abstract: An integrated process for making furan-2,5-dicarboxylic acid (FDCA) and FDCA derivatives combines a furfural oxidation reaction, an intermediate water removal step, and a furoate salt carboxylation reaction. A furfural feed stream is oxidized with an alkaline solution in the presence of a catalyst and excess base with air as the oxidant. The resulting furoate solution from the first process step is dried to remove water. The anhydrous solid products are sent to a carboxylation process to produce FDCA salt, which can optionally be further reacted to form FDCA or FDCA ester.
