生物基聚合物单体二元羧酸合成的研究进展

Research progress in production of bio-based polymeric monomers dicarboxylic acids

为应对能源危机和环境问题,发展生物基新材料部分替代传统石油基材料,对减少化石能源的依赖和降低碳排放量具有重要意义。二元羧酸是一类非常重要的高附加值化学品,可用于生产尼龙、聚氨酯、聚酯、可降解塑料等聚合物材料。总结了国内外研究人员在生物基单体二元羧酸研究领域的最新进展,重点介绍了丁二酸、戊二酸、己二酸、壬二酸和癸二酸的合成路线和方法,深入剖析了反应体系中的反应机理,以期为生物基二元羧酸的工业化生产提供思路。

Production of renewable chemicals and materials from abundant biomass can alleviate our dependence on the depleting fossil resources and reduce carbon emissions,which has attracted increasing attention until now.Dicarboxylic acids are an important class of high value-added chemicals that have been widely used to synthesize polymer materials such as nylons,polyurethanes,polyesters,and especially degradable plastics.In this review,the latest progress in the synthesis of bio-based polymeric monomers dicarboxylic acids at home and abroad was summarized.Various routes and methods for synthesis of succinic acid,glutaric acid,adipic acid,azelaic acid and sebacic acid,as well as the underlying mechanism in the respective reaction systems,were discussed.This review may provide new ideas for the further development of industrial production of dicarboxylic acids derived from biomass.
