Title (EN) OLIGOMERS OF FDCA AND GLYCOLS FROM A ONE-POT ESTERIFICATION-TRANSESTERIFICATION PROCESS USING WATER-TOLERANT METAL TRIFLATE CATALYST
(FR) OLIGOMÈRES DE FDCA ET DE GLYCOLS ISSUS D'UN PROCÉDÉ MONOTOPE D'ESTÉRIFICATION-TRANSESTÉRIFICATION UTILISANT UN CATALYSEUR À BASE DE TRIFLATE MÉTALLIQUE TOLÉRANT À L'EAU
Abstract:
(EN) A method for preparing sugar-based oligomers is described. The process involves sequential (one-pot) esterification of 2,5-furan-dicarboxylic acid (FDCA) with an alcohol and transesterification with a glycol, as catalyzed by relatively low amounts of homogeneous water-tolerant Lewis acid catalysts, which can be retained in the product mixture from the esterification through transesterification.
(FR) La présente invention concerne un procédé de préparation d'oligomères à base de sucre. Le procédé consiste en une estérification séquentielle (monotope) d'acide 2,5-furan-dicarboxylique (FDCA) avec un alcool et une transestérification avec un glycol, catalysées par des quantités relativement faibles de catalyseurs à base d'acide de Lewis homogènes tolérants à l'eau, qui peuvent être retenus dans le mélange de produit issu de l'estérification et de la transestérification.
