Abstract
The present invention is directed to a process for the synthesis of 2,5-furandicarboxylic acid (FDCA) comprising the steps of: (1) oxidising an aqueous solution of 5 hydroxymethylfurfural (HMF) in the presence of molecular oxygen, of a heterogeneous catalyst comprising ruthenium and of a strong base at a temperature above 100° C., obtaining a reaction product in aqueous solution comprising a salt of FDCA acid; (2) separating said heterogeneous catalyst from said reaction product in aqueous solution, and (3) re-using said heterogeneous catalyst in the oxidation reaction in step (1).
