生物质基碳水化合物催化转化制备乳酸的研究进展

生物质基碳水化合物（纤维素、淀粉、葡萄糖、果糖等）是自然界最丰富的可再生资源，将其用于生产人类生存所必需的有机化学品是当前的一个重要研究方向。其中，将生物质催化转化为乳酸及其衍生化学品是生物质高值利用的途径之一，并在近年的研究中取得了显著进展。本文对生物质基糖类催化转化制备乳酸进行了详细的总结和评述，着重分析了葡萄糖转化为乳酸的转化过程及催化剂研究，讨论了葡萄糖异构化及果糖逆醛醇反应的催化剂机理，并对今后该领域的研究前景进行了展望。

Advances in Catalytic Conversion of Biomass Derived Carbohydrates into Lactic Acid

Biomass derived carbohydrates (cellulose, starch, glucose, fructose) is the most abundant renewable resource, which is also viewed as carbon source for producing liquid fuel and platform chemicals in the future. Selectively convert the biomass resources into lactic acid and lactate with some catalysts under hydrothermal condition is one route for higher value application of biomass resources. This paper reviewed some recent research advances in the catalytic synthesis of lactic acid from carbohydrates, with an emphasis on the chemical reaction process and the catalysts. The isomerization mechanics of glucose and retro-aldol condensation mechanism of fructose were discussed. The future research tendency in this field was concluded.
