Title (EN) METHODS FOR PREPARING 2,5-FURANDICARBOXYLIC ACID
(FR) PROCÉDÉS POUR PRÉPARER L'ACIDE 2,5-FURANEDICARBOXYLIQUE
Abstract: front page image
(EN)Provided are methods of producing 2,5-furandicarboxylic acid (FDCA) from renewable sources such as seaweed, alginate, oligoalginate, pectin, oligopectin, polygalacturonate, galacturonate, and/or oligogalacturonate. The sugars in the renewable sources can be converted into one or more intermediates such as 4-deoxy-L-erythro-5- hexoseulose uronate (DEHU), 4-deoxy-L-threo-5-hexosulose uronate (DTHU), 5- hydroxymethyl furfural (HMF), 2,5-dihydroxymethyl furan (DHMF), and 5-formyl-2- furancarboxylic acid (FFA), which can be converted into FDCA by dehydration and cyclization to produce 5-formyl-2-furancarboxylic acid (FFA), followed by oxidation to produce FDCA. DEHU or DTHU may also be converted into FDCA by oxidation to produce 2,3-dihydroxy-5-oxohexanedioic acid (DOHA), which then undergoes dehydration and cyclization to produce FDCA.
(FR)La présente invention concerne des procédés de production d'acide 2,5-furanedicarboxylique (FDCA) à partir de sources renouvelables telles que des algues, un alginate, un oligoalginate, la pectine, l'oligopectine, un polygalacturonate, le galacturonate, et/ou un oligogalacturonate. Les glucides dans les sources renouvelables peuvent être convertis en un ou plusieurs intermédiaires tels que 4-désoxy-L-érythro-5-hexose-ulose-uronate (DEHU), 4-désoxy-L-thréo-5-hexosulose-uronate (DTHU), 5-hydroxyméthylfurfural (HMF), 2,5-dihydroxyméthylfurane (DHMF), et acide 5-formyl-2-furanecarboxylique (FFA), qui peuvent être convertis en FDCA par déshydratation et cyclisation pour produire l'acide 5-formyl-2-furanecarboxylique (FFA), suivi par une oxydation pour produire FDCA. DEHU ou DTHU peuvent également être convertis en FDCA par oxydation pour produire l'acide 2,3-dihydroxy-5-oxohexanedioïque (DOHA), qui subit ensuite une déshydratation et une cyclisation pour produire FDCA.
