Abstract
The present invention refers to a process for production of a mixture including 2,4-furandicarboxylic acid (2,4-FDCA) and 2,5 furandicarboxylic 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.
