Aerobic oxidation of biomass derived 5-hydroxymethylfurfural into 5-hydroxymethyl-2-furancarboxylic acid catalyzed by a montmorillonite K-10 clay immobilized molybdenum acetylacetonate complex

Aromatic polymers such as poly(ether sulfone), poly(ether ketone), and polyimide have been widely used in industry due to their thermal, mechanical, and chemical stabilities. Although their application to catalysis has been limited, the introduction of a hyperbranched architecture to such aromatic polymers is effective in developing catalytic materials that combine the advantages of homogenous and heterogeneous catalysts. This review article overviews the recent progress on the design and synthesis of hyperbranched aromatic polymers. Several acid catalyzed reactions and the aerobic oxidation of alcohols have been demonstrated using hyperbranched aromatic polymers as catalysts. The advantage of hyperbranched polymers against linear polymers is also discussed.

p-Nitrobenzoic acid could be efficiently prepared from aerobic oxidation ofp-nitrotoluene using manganese dioxide (MnO2) andN-hydroxyphthalimide (NHPI) as catalysts. The conditions of oxidation were also optimaized: 97 % conversion ofp-nitrotoluene and 89 % isolated yield ofp-nitrobenzoic acid could be obtained at 110 °C under 0.4 MPa for 4 h in presence of 10 mol% NHPI and 10 mol% MnO2.
