Abstract:
The invention is directed to the to the electrochemical preparation of 2,5-furandicarboxylic acid (FDCA) from 5-hydroxymethylfurfural (HMF) by electrochemical oxidation, comprising a first oxidation step of oxidizing HMF to 5-hydroxymethyl-2-furan-carboxylic acid (HMFCA) in an electrochemical cell, subsequently a first isolation step of isolating HMFCA, followed by a second oxidation step of HMFCA to FDCA.
