Abstract

A series of novel ionic liquids based on glucose was synthesized in high yields in simple two or three-step reaction procedures. These carbohydrate-based ionic liquids were studied and compared to commercially available imidazolium-based ionic liquids as supports for Novozym 435 in the acrylation of n-butanol. A direct correlation between the availability of hydroxy groups and the overall activity as well as an enhanced recyclability of the biocatalyst has been found for the glucose-based ionic liquids.

摘要

一系列基于葡萄糖的新型离子液体通过简单的两步或三步反应在高产率下合成。这些基于碳水化合物的离子液体与市售的基于咪唑的离子液体作为 Novozym 435 在正丁醇酯化反应中的支撑相进行了研究和比较。发现基于葡萄糖的离子液体的羟基可用性与整体活性之间存在直接相关性，并且生物催化剂的可回收性得到增强。
