Abstract

The oxidation reaction of 5-hydroxymethylfurfural to the bioplastic monomer 2,5-furandicarboxylic acid over heterogenous resin-supported Pt catalysts was investigated in detail, under continuous flow, base-free conditions, and in neat water. The product was continuously obtained in 99 % yield by running the reaction at 120 °C, 303 s residence time, 1.2 mL min^-1 O₂ flow rate, and 7.7 bar O₂ pressure. The product was isolated with a high space-time-yield of 46.0 g L^-1 h^-1 without purifications or acid/base treatments.

Keywords: 2,5-furandicarboxylic acid; continuous flow; green chemistry; heterogeneous catalysis; water chemistry.
