ABSTRACT

Alkanediols with five and six carbon atoms (1,2- & 1,5-pentanediols and 1,2- & 1,6-hexanediols, respectively) are an important class of industrial chemicals having wide application. Their production from lignocellulosic biomass-derived furfural and its derivatives using solid catalysts is a sustainable and attractive approach. Several bifunctional catalysts with metal (for hydrogenation/hydrogenolysis) and acid/base (for ring opening) functionalities have been reported. Effective and selective conversion of furfurals to a desired diol is still a challenge. This review discusses the recent advances in catalyst development for pentane- and hexanediols. The reaction pathways, active sites, and possible reaction mechanisms over the solid catalysts are discussed. A comparative catalytic activity data of the known catalysts are reported.

摘要

具有五个和六个碳原子的烷二醇（分别为1,2-和1,5-戊二醇和1,2-和1,6-己二醇）是一类具有广泛应用的重要工业化学品。使用固体催化剂从木质纤维素生物质衍生的糠醛及其衍生物进行生产是一种可持续且有吸引力的方法。已经报道了几种具有金属（用于氢化/氢解）和酸/碱（用于开环）官能团的双官能催化剂。糠醛有效和选择性地转化为所需的二醇仍然是一个挑战。这篇综述讨论了戊二醇和己二醇催化剂开发的最新进展。讨论了固体催化剂上的反应途径，活性位点和可能的反应机理。报告了已知催化剂的比较催化活性数据。
