摘要
在如今能源危机以及环境污染的大背景下,生物质作为一种能够代替化石燃料的可再生能源之一,如何将生物质催化转化为有价值的己醇和己二醇在生物质转化领域受到了广泛的研究关注.己醇和己二醇被认为是一种具有高度工业价值的C6醇,其中己二醇在聚酯工业发展的领域有重要的作用,己醇则被认为是一种合适的替代燃料.本文根据原料和不同催化剂对生物质基制备己醇和己二醇的研究工作进行了归纳总结,系统阐述了近年来通过纤维素基、5-羟甲基糠醛及其衍生物、己二酸及其酯类等生物质基催化转化制备己醇和己二醇的研究进展,分析了 1,6-己二醇在催化制备C6化合物(ε-己内酯、己二酸、6-羟基己酸和己二胺)方面的应用,并在此基础上对催化加氢制备己醇和己二醇的发展趋势进行了展望,为未来进一步绿色地生产可持续的C6化合物提供理论指导和有益参考.
Abstract
Given the current energy crisis and concerns regarding environmental pollution,biomass is considered as a sustainable energy source that can potentially replace fossil fuels,and extensive research of biomass conversion has been directed towards the catalytic transformation of biomass into valuable hexanol and hexanediol.Hexanol and hexanediol are regarded as highly industrially valuable C6 alcohols,with hexanediol playing a crucial role in polyester industry,and hexanol being considered as a suitable alternative fuel.This review provided a comprehensive overview of biomass-derived production of hexanol and hexanediol,considering various feedstocks and catalytic approaches.It systematically outlined recent advancements in the catalytic conversion of biomass-derived compounds,such as cellulose-based substrates,5-hydroxymethylfurfural and its derivatives,as well as hexanedioic acid and its esters,into hexanol and hexanediol.The review also summarized the applications of 1,6-hexanediol in the catalytic synthesis of C6 compounds(ε-caprolactone,adipic acid,6-hydroxycaproic acid,and hexanediamine).Furthermore,it provided an outlook on the future trends in catalytic hydrogenation for producing hexanol and hexanediol,aiming to offer theoretical guidance and valuable insights for the eco-friendly and sustainable production of C6 compounds.
