Title (EN) PROCESS FOR PRODUCING 2,5-FURANDICARBOXYLIC ACID DIALKYL ESTER
(FR) PROCESSUS DE PRODUCTION DE DIALKYLESTER D’ACIDE 2,5-FURANEDICARBOXYLIQUE
Abstract:
(EN) 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.
(FR) La présente invention concerne des processus de production de dialkylester d’acide 2,5-furanedicarboxylique. Selon un mode de réalisation, le processus consiste a) à mettre en contact de l’acide 2,5-furanedicarboxylique, de l’alcool en excès, et optionnellement un catalyseur dans un réacteur à une température comprise entre 50 °C et 325 °C et à une pression comprise entre 1 bar et 140 bar pour former une composition en phase liquide comprenant un ester d’acide 2,5-furanedicarboxylique, l’alcool et de l’eau ; b) à abaisser la température de la composition en phase liquide pour former un ester d’acide 2,5-furanedicarboxylique cristallisé cru ; c) à séparer le produit de l’étape b) pour former une phase solide comprenant un ester purifié d’acide 2,5-furanedicarboxylique et une liqueur mère comprenant de l’alcool et de l’eau ; et d) à retirer au moins une partie de l’eau de la liqueur mère. Selon un mode de réalisation, l’acide 2,5-furanedicarboxylique est mis en contact avec une source d’alcool et optionnellement un catalyseur.
