PRODUCTION OF PURIFIED DIALKYL-FURAN-2,5-DICARBOXYLATE (DAFD) IN A RETROFITTED DMT PLANT

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 dialkyi furan dicarboxylate (DAFD), unreacted alcohol, 5-(alkoxycarbonyl)fu...

Zusammenfassung: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 dialkyi furan dicarboxylate (DAFD), unreacted alcohol, 5-(alkoxycarbonyl)furan-2- carboxylic acid (ACFC), and alkyl furan-2-carboxylate (AFC). The esterification zone comprises at least one reactor that has been previously used in an DMT process.
