有机二元酸是重要的化工原料和聚酯单体.以生物基平台化合物为原料,发展催化氧化制备有机二元酸的新方法,有可能提供一条不依赖化石资源制备有机二元酸的技术路线.本文结合本研究组在该方向的近期研究进展,阐述了苹果酸氧化裂解制备丙二酸(酯)、乙酰丙酸酯氧化裂解制备丁二酸(酯)、糠醛及5-羟甲基糠醛等呋喃衍生物氧化裂解制备马来酸和马来酸酐、5-羟甲基糠醛选择氧化制备2,5-呋喃二甲酸等反应,探索了催化材料选取对催化氧化产物选择性控制的重要性,并对生物质催化制备有机二元酸的研究及发展前景进行了分析.

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.
