摘　　要：环己烯、正己烯、正辛烯等C_(6)~C_(8)烯烃是重要的化工原料,用途广泛。综述了环己烯及正己烯,正辛烯等C_(6)~C_(8)烯烃水合催化剂的研究进展。环己烯水合法制备环己醇是一种绿色制备工艺,其催化剂由最初的硫酸、磺酸等均相催化剂逐渐向分子筛等非均相催化剂过渡,其中HZSM-5分子筛以其高选择性、高活性成为工艺上常用的催化剂。环己烯间接水合法合成环己醇的途径具有高选择性,高转化率,低能耗的优点,其催化剂的研究也处在一个高速发展阶段。正己烯、正辛烯水合催化剂的研究较少。未来离子液体等新型水合催化剂将会成为环己烯水合制备环己醇的研究重点。Cyclohexene,n-hexene,n-octene and other C_(6)-C_(8) olefins are important chemical materials widely used.The research progress in cyclohexene,n-hexene,n-octene and other C_(6)-C_(8) olefin hydration catalysts was reviewed.The preparation of cyclohexanol by cyclohexene hydration is a kind of green preparation process.Its catalyst gradually transits from homogeneous catalyst such as sulfuric acid and sulfonic acid to heterogeneous catalyst such as molecular sieve.HZSM-5 molecular sieve has become a commonly used catalyst due to its high selectivity and activity.The synthesis of cyclohexanol by indirect hydration of cyclohexene has the advantages of high selectivity,high conversion and low energy consumption,and the research of its catalysts is also in a high-speed development stage.The research will be focused on the new hydration catalysts of ionic liquid for cyclohexene hydration to cyclohexanol in the future when there is less research on n-hexene and n-octene hydration catalyst.
