Process for the production of a mixture of 2,4- furandicarboxylic acid and 2,5- furandicarboxylic acid (FDCA) via disproportionation reaction, mixture of 2,4-FDCA and 2,5-FDCA obtainable thereby, 2,4-FDCA obtainable thereby and use of 2,4-FDCA

摘要

The present invention refers to a process for production of a mix¬ ture comprising 2,4-furandicarboxyiic acid (2,4-FDCA) and 2,5 furandicar- boxyiic acid (2,5-FDCA) through the disproportionation route, using as base compounds oxidation products of furfural. This invention also relates to a process for production of 2,4-FDCA as a result of a disproportionation route and the use of 2,4- FDCA as a monomer or comonomer to synthesize esters or any compounds which can generate macromolecules, such as polyesters.
