英文摘要:

      With the tightening supply of petroleum resources and the advent of energy transition, research on renewable bio-based chemicals and their derivatives has been attracting increasing attention. As a bio-based diol,isosorbide is expected to serve as a substitute for petroleum-based raw materials and find extensive applications in fields such as polymers. Thus, it has received much attention in recent years. The acid catalyzed dehydrocyclisation of sorbitol is the core step in the synthesis of isosorbide, and various catalyst systems suitable for the dehydration of sugar alcohols have been explored. This article reviews the homogeneous and heterogeneous acidic catalyst systems reported in recent years, introduces the characteristics of homogeneous and heterogeneous catalysts, discusses the advantages and disadvantages of different catalytic systems, and envisages the research of catalytic systems and development of chemical process.
