Title (EN) OLIGOMERIZATIONS OF FDCA AND GLYCOLS IN A ONE-POT ESTERIFICATION-TRANSESTERIFICATION PROCESS CATALYZED BY HOMOGENEOUS ORGANOMETALLIC LEWIS ACIDS
(FR) OLIGOMÉRISATIONS DE FDCA ET DE GLYCOLS DANS UN PROCÉDÉ MONOTOPE D'ESTÉRIFICATION-TRANSESTÉRIFICATION CATALYSÉ PAR DES ACIDES DE LEWIS ORGANOMÉTALLIQUES HOMOGÈNES
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 loadings of homogeneous organometallic Lewis acids, 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 implique l'estérification séquentielle (monotope) d'acide 2,5-furan-dicarboxylique (FDCA) avec un alcool et la transestérification avec un glycol, ledit procédé étant catalysé par des charges relativement faibles d'acides de Lewis organométalliques homogènes, qui peuvent être retenus dans le mélange de produits issu de l'estérification et de la transestérification.
