中文摘要： 针对目前环己烯直接水合制备环己醇工艺存在反应速率慢、转化率低等缺点，本项目拟利用离子液体和杂多酸的优异性能，合成具有双亲功能的杂多酸型离子液体，并结合强化喷射混合技术，促进环己烯直接水合的反应速率，提高环己醇收率。通过深入研究功能化杂多酸型离子液体结构与催化活性之间的构效关系，筛选出适合环己烯水合的高性能催化剂，并在强化喷射湍流条件下系统研究环己烯水合反应动力学的影响因素，建立合理的反应动力学模型，结合多尺度理论，阐明强化喷射混合技术对环己烯水合反应的作用机制，揭示湍流微观混合与反应之间的相互关系，为环己醇的清洁、高效合成提供重要理论基础。

英文摘要： At present, there is disadvantage of the low reaction ratio on direct hydration of cyclohexene to cyclohexanol. With the excellent performance of ionic liquids (ILs) and heteropoly acids, amphiphilic heteropolyanion-based ionic liquids will be synthesized. An intensified jet mixing technology will be also introduced to increase hydration reaction rate. The stucture-activity relationship between the structures and catalytic activies of task-specific heteropolyanion-based ionic liquids will be studied in depth, and the catalysts with good activity will be choosen for the hydration of cyclohexene. The effect of various parameters on the kinetics of the hydration of cyclohexene will be studied in detail. The reaction kinetics model of the hydration of cyclohexene will be proposed. The mutliscale theory will be used to explain the mechanisms of action of the intensified jet mixing technology and the interaction between turbulent mixing and reaction. The studies about this work will provide important theoretical basis for the production of cyclohexanol with the advantages of cleanliness and high-efficiency.
