摘　　要：生物质基2,5-呋喃二甲醇(BHMF)可从廉价易得的糖类出发,经催化转化-选择性氢化制取,并作为一种用途广泛的化工中间体及燃料前体,尤其在改善传统聚酯性能以及合成绿色可降解的生物基聚酯新材料方面具有独特优势。BHMF制取过程中,传统的氢化方式消耗了大量高品位能源氢气,且高压氢气存在安全隐患并导致基础设施投入多。本工作立足于催化转移氢化的优势,综述了甲酸、醇类及其他类型氢供体通过催化转移氢化的方式选择性加氢制取BHMF的研究进展;并针对催化转移氢化过程中不同类型氢供体、催化剂和反应工艺的特点及存在的问题,分析了反应条件、强化手段等对BHMF选择性和收率的影响以及反应体系的优劣。在此基础上,提出了转移氢化制取BHMF新型催化体系的研究方向,并对清洁高效、本质安全BHMF制取工艺的发展进行了展望,为生物质转化中特定催化体系的研发提供科学参考。Biomass-based 2,5-bis(hydroxymethyl)furan(BHMF)is one of the important high value-added chemicals,which can be prepared from inexpensive and renewable carbohydrates through the way of catalytic conversion and selective hydrogenation,and as a widely used chemical intermediate and fuel precursor,it has unique advantages in improving the performance of traditional polyesters and synthesizing new biodegradable bio-based polyesters.In recent years,the research on the production of high value-added chemicals such as BHMF from carbohydrate has been attracting much attention from both academia and industry.However,cleanliness,high efficiency,high selectivity and low-cost remain key challenges in this area,especially for practical applications.In the process of BHMF production,the traditional hydrogenation method consumed a large amount of high-grade energy of hydrogen,and an excessive investment in infrastructure would be generated due to the security risks of higher pressure of hydrogen.On account of the advantages of catalytic transfer hydrogenation,the advances in selective hydrogenation to prepare BHMF using formic acid,alcohols and other types of hydrogen donors by the approach of catalytic transfer hydrogenation is systematically discussed in this review.In view of the features and problems of different types of hydrogen donors,catalysts and reaction processes during the catalytic transfer hydrogenation process,the effects of reaction conditions and process intensifications on the selectivity and yield of BHMF,and the merits and demerits of the reaction system were all investigated.On this basis,the future directions of new catalytic systems for preparation of BHMF by transfer hydrogenation is proposed,and the cleaner,more efficient and essential safety technologies for the production of BHMF is predicted,which will provide some scientific reference for the research and development of related catalytic systems in biomass conversion.
