摘 要
离子液体作为一种新型绿色溶剂和催化剂,在化学合成领域展现出独特优势。传统有机溶剂存在挥发性、易燃性和环境污染等问题,而离子液体具有低挥发性、高热稳定性和可设计性等特性,为解决上述问题提供了新思路。本研究旨在系统探讨离子液体在不同类型化学合成反应中的应用潜力,通过实验设计与理论计算相结合的方法,选取典型有机合成反应体系,考察不同结构离子液体对反应活性、选择性和产物收率的影响。研究发现,特定结构的离子液体能够显著提高某些反应的选择性和收率,如在Diels - Alder反应中,以含氮杂环类离子液体为介质时,反应速率加快且区域选择性增强;在酯化反应里,酸性功能化的离子液体表现出优异的催化性能。此外,还探索了离子液体回收再利用的可能性,结果表明经过简单处理后的离子液体仍能保持较高活性。

Abstract
As a new green solvent and catalyst, ionic liquid shows unique advantages in the field of chemical synthesis. Traditional organic solvents have problems such as volatility, flammability and environmental pollution, while ionic liquids have the characteristics of low volatility, high thermal stability and designability, which provides a new idea for solving the above problems. The purpose of this study is to systematically explore the application potential of ionic liquids in different types of chemical synthesis reactions, combine experimental design with theoretical calculation, and select a typical organic synthesis reaction system to investigate the influence of ionic liquids with different structures on the reactivity, selectivity and product yield. It is found that the specific structure of the ionic liquid can significantly improve the selectivity and yield of some reactions, such as in the Diels-Alder reaction, with the nitrogen-containing heterocyclic ionic liquid as the medium, the reaction rate is accelerated and the regional selectivity increases; in the esterification reaction, the acidic functional ionic liquid shows excellent catalytic performance. Moreover, the possibility of ionic liquid recycling was explored, and the results showed that the ionic liquid could still maintain high activity after simple treatment.
