| 摘要 | An integrated process is described for producing 2,5-furandicarboxylic acid and/or a derivative thereof from a six carbon sugar-containing feed, comprising: a) dehydrating a feed comprising a six-carbon sugar unit, in the presence of a bromine source and of a solvent, to generate an oxidation feed comprised of at least one of 5-hydroxymethylfurfural and/or a derivative or derivatives of 5-hydroxymethylfurfural in the solvent, together with at least one bromine containing species; b) contacting the oxidation feed from step (a) with a metal catalyst and with an oxygen source under oxidation conditions to produce an oxidation product mixture comprising 2,5-furandicarboxylic acid (FDCA) and/or a derivative thereof, the solvent, and a residual catalyst; c) purifying and separating the mixture obtained in step (b) to obtain FDCA and/or a derivative thereof and the solvent; and d) recycling at least a portion of the solvent obtained in step (c) to step (a). | ||||||
