摘　　要：环己醇作为化学工业的关键中间体,主要用来合成聚酰胺、己二酸和己内酰胺等酰胺类物质,其制备主要通过环己烯和水的加成反应。相对于传统制备环己醇的方法,环己烯水合法由于安全性高、工艺流程简单、反应绿色环保成为目前主流研究方向。环己烯水合生成环己醇的反应是一个酸催化反应,可以使用矿物酸、苯磺酸、强酸性离子交换树脂、分子筛等作为催化剂。分子筛由于具有适宜的酸性、高的机械强度和热稳定性、好的择形性等特点而成为水合用催化剂的研究重点。其中HZSM-5分子筛,其孔道直径与环己烯和环己醇的分子直径大小相当,因此对水合反应的择形选择性很好。而通过对HZSM-5分子筛进行改性,在适宜的反应条件下,环己醇的产率和选择性均得到显著提高,这类型的材料正在得到越来越广泛的应用。Cyclohexanol,as a key intermediate in the chemical industry,is mainly used to synthesize polyamide,adipic acid,caprolactam and other acyl acids amines,which are prepared mainly by the addition reaction of cyclohexene and water.Compared with the traditional methods for preparing cyclohexanol,cyclohexene water method has become the mainstream research direction because of its high safety,simple process flow and green reaction.The reaction of cyclohexene hydration to cyclohexanol is an acid-catalyzed reaction,which can use mineral acids,benzene sul-fonic acid,strong acid ion exchange resin,molecular sieve as catalysts.Molecular sieves have become the focus of research on hydration catalysts because of their suitable acidity,high mechanical strength and thermal stability,and good shape selection.The pore diameter of HZSM-5 molecular sieve is similar to the molecular diameter of cyclohexene and cyclohexanol,so it has good shape selection selectivity for hydration reaction.By modi-fying HZSM-5 molecular sieve,the yield and selectivity of cyclohexanol are significantly improved under suitable reaction conditions,and this type of material is being more and more widely used.
