生物基聚酯单体的定向催化制备

Dicarboxylic acid is an important polyester monomer, which is widely used in all aspects of chemical fiber, light industry, electronics and other industrial production. With the development of social industrialization, the production of dicarboxylic acids from a large number of non-renewable petroleum resources has caused the lack of oil resources and environmental pollution of the earth. The preparation of high value-added chemicals dicarboxylic acids by biomass and its derivatives has attracted extensive attention in chemical applications. In the research of synthetic biomass dicarboxylic acid, it is of great significance to design and prepare catalysts with high activity and high stability. In recent years, many works have explored the types of catalysts and made certain research progress. In this review, the catalytic system for the preparation of C-3 similar to C-6 dicarboxylic acid, including malonic acid, succinic acid, 2,5-furandicarboxylic acid and adipic acid, was reviewed from the aspects of biomass raw materials, catalyst performance evaluation and reaction mechanism, and the development of biomass dicarboxylic acid preparation is prospected.
