摘要：近年来,随着化石资源的日益枯竭,对可再生资源——生物质及其衍生物的研究越来越受到人们的重视.尤其是葡萄糖的加氢产物——山梨醇,已经成为重要的生物质转化平台化合物而受到人们极大的关注.山梨醇可以通过一次脱水生成1,4-脱水山梨醇,也可以通过二次脱水反应生成异山梨醇,而这两种脱水产物都是非常重要的化工原料.本文对山梨醇催化选择性脱水方面的新进展进行了简要评述,最后简要总结了该领域的发展趋势.
Recently,the use of renewable biomasses has attracted much attention from academics and industry.Sorbitol is a useful biomassderived chemical that can be converted to high-added-value products;it can be conveniently obtained from cellulose via glucose.Isosorbide and 1,4-anhydrosorbitol,which can be produced by dehydration of sorbitol,are potentially important bio-based industrial chemicals.Sorbitol can be transformed into 1,4-anhydrosorbitol and isosorbide through acid-catalyzed selective dehydration.The catalyst acidity is the most important factor in acid-catalyzed dehydration reactions.It has been observed that strong acidity is favorable for producing isosorbide.Various homogeneous and heterogeneous catalysts have been developed for sorbitol dehydration,depending on the desired products.Mineral acids such as sulfuric acid and hydrochloric acid,and metal halides such as Sn Cl4 and Al Cl3 are efficient catalysts for sorbitol dehydration.However,processes using homogeneous acids have drawbacks from environmental and safety perspectives.Moreover,homogenous catalyst separation from the reaction mixture is cumbersome,which may add extra costs to commercial synthesis.Various solid catalysts such as zeolites,metal(IV)phosphates,layered niobiummolybdate,tungstophosphoric acids supported on various metal oxides,metal oxides modified with phosphoric acid,a superhydrophobic mesoporous polymer-based acid catalyst,and resins(amberlyst-15)have recently been tested in the selective dehydration of sorbitol.In addition,high-temperature liquid water has attracted much attention as a promising reaction medium for sorbitol dehydration.Future prospects for catalytic dehydration of sorbitol are summarized.
