摘要
催化剂的选择及制备工艺对环己烯的制备有很大的影响。该文采用强酸性阳离子交换树脂作催化剂,使环己醇进行气相脱水制备环己烯,可避免用浓硫酸或浓磷酸催化造成的环境污染,而且产率高,催化剂可重复使用。既可强化学生的环保意识,又可使学生掌握绿色化学的实用技术。
The preparation process of cyclohexene is concerned greatly with catalyst and technique. A new method of preparing cyclohexene with strong acid polystyrene cation exchange resin as catalyst was discussed. This method can prevent the environmental pollution caused by strong liquid acid. It also has high yield and the catalyst can be used repeatedly. Using this method students can raise their consciousness of environmental protection and master practical techniques of green-chemistry.
