摘要
5-羟甲基糠醛(HMF)是一种重要的生物基平台化合物,被美国能源部评为 12 种最具潜力的生物基平台化合物之一.制取 HMF 最有效的方法是酸催化己糖脱水,己糖在自然界中数量有限,而纤维素在自然界中广泛存在,直接以纤维素为原料制备 HMF 避免了己糖的分离,具有更高的经济效益.纤维素由于其特殊的化学结构,不溶于水和一般的有机溶剂,反应活性较低,纤维素转化为 HMF 首先的障碍是纤维素的水解.文章从纤维素结构出发,基于纤维素催化转化制备HMF的反应机理,综述了近年来纤维素制备HMF中纤维素预处理的方法、溶剂体系、催化剂体系的研究进展,并对纤维素制备HMF的发展前景进行了展望,以期为相关研究工作提供一定的参考.
Abstract
5-hydroxymethylfurfural(HMF)is an important bio-based platform chemical and was chosen as one of the top 12 value-added bio-based chemicals by the U.S.Department of Energy.The effective method for preparation HMF is the acid-catalyzed dehydration of hexoses which are limited in resources.Cellulose is widely available in nature.Using cellulose for HMF synthesis avoids the isolation of monosaccharides,and is considered as more cost-effective.Cellulose is low in reactivity and insoluble in water and general organic solvents due to its special chemical structure.The first significant barrier for the conversion of cellulose to HMF is the hydrolysis of cellulose.Based on cellulose structure and the mechanism of catalytic conversion of cellulose into HMF,known and emerging pretreatment methods,solvent systems,and catalyst systems in the conversion of cellulose into HMF in recent years are summarized.This review aims to provide references for further in-depth development of HMF production directly from cellulose and guidance for future conversion.
