Abstract
A method for synthesizing 2,5-furandicarboxylic acid (FDCA) from furan-2,5-dialdehyde (DFF). The method is industrially applicable due to the simplicity and availability of the reagents used, and due to the experimental conditions on which the method is based: the method requires low temperatures and enables a reaction under atmospheric pressure, the reaction times being relatively short. Furthermore, the method does not lead to the formation of salts that need to be treated downstream from the method, and the catalytic ratio relative to the initial product is particularly low.
