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).

摘要： Disclosed herein are processes for producing 2,5-furandicarboxylic acid dialkyl ester. In one embodiment, the process comprises a) contacting 2,5-furan dicarboxylic acid, excess alcohol, and optionally, a catalyst in a reactor at a temperature in the range of from 50°C to 325°C and a pressure in the range of between 1 bar to 140 bar to form a liquid phase composition comprising an ester of 2,5-furan dicarboxylic acid, the alcohol and water; b) lowering the temperature of the liquid phase composition to form a crude crystallized ester of 2,5-furan dicarboxylic acid; c) separating the product of step b) to form a solids phase comprising a purified ester of 2,5-furan dicarboxylic acid and a mother liquor comprising alcohol and water; and d) removing at least a portion of the water from the mother liquor. In one embodiment, the 2,5-furan dicarboxylic acid is contacted with an alcohol source and optionally, a catalyst.
摘要翻译：本文公开了制备2,5-呋喃二羧酸二烷基酯的方法。在一个实施方案中，该方法包括：a）将反应器中的2,5-呋喃二羧酸，过量醇和任选的催化剂在50℃至325℃的温度范围内接触，在1巴至140巴之间以形成包含2,5-呋喃二羧酸的酯，醇和水的液相组合物; b）降低液相组合物的温度以形成2,5-呋喃二羧酸的粗结晶酯; c）分离步骤b）的产物以形成包含2,5-呋喃二羧酸的纯化酯和包含醇和水的母液的固体相; 和d）从母液中除去至少一部分水。在一个实施方案中，2,5-呋喃二羧酸与醇源和任选的催化剂接触。
