催化氧化制备生物基有机二元酸研究进展

Dicarboxylic acid is of great importance in chemical industry and widely used as polyester monomer. Exploration of novel method for catalytic synthesis of dicarboxylic acid from biomass-derived platform molecules could provide a fossil resource independent route. Herein, catalytic oxidation of malic acid into malonate, levulinate/furfural into succinate, and furfural/5-hydroxymethylfurfural into maleic acid (anhydride) through oxidative C-C bond cleavage are reviewed on the basis of the authors' recent work. Selective oxidation of 5-hydroxy-methylfurfural into 2,5-diformylfuran/2,5-furandicarboxylic acid are also described. Furthermore, the prospects of synthesis of dicarboxylic acid using bio-based platform molecules as feedstocks are also outlooked.
