Abstract

The present disclosure provides processes for the production of 2-5-furandicarboxylic acid (FDCA) and intermediates thereof by the chemocatalytic conversion of a furanic oxidation substrate. The present disclosure further provides processes for preparing derivatives of FDCA and FDCA-based polymers. In addition, the present disclosure provides crystalline preparations of FDCA, as well as processes for making the same.
