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...

Summary: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. 公开了一种生产包含呋喃-2,5-二甲酸二烷基酯（DAFD）的纯化蒸气的方法。呋喃-2,5-二甲酸（FDCA）和醇在酯化区中，生成粗制二酯物流，其含有呋喃二甲酸二烷基酯（DAFD）、未反应的醇、5-(烷氧基羰基)呋喃-2-甲酸（ACFC）和呋喃-2-甲酸烷基酯（AFC）。酯化区包括至少一个先前已用于DMT工艺的反应器。
