摘要
离子液体由于具有特殊的性质,包括低挥发性、大极性、良好的热稳定性及溶解性和酸碱性可调等特点, 引起了人们极大的兴趣,与传统有机溶剂反应相比,离子液体具有选择性好,后处理简单及回收后可多次重复使用等优点,作为反应介质或催化剂被广泛应用于有机合成中。酯化反应是一类重要的有机反应,其催化技术也在不断发展。本文简单介绍了离子液体的分类、合成及应用,综述了各类离子液体作为催化剂在酯化反应中的应用研究,并对其未来的发展进行了展望。

Abstract
Ionic liquids (ILs) are applied to anic reaction systems as “green solvents” and catalysts due to their unique properties, including low volatility, high polarity, good thermal stability over a wide temperature range and selective dissolving capacity by a proper choice of cations or anions. Compared with anic solvents, ionic liquids have great advantages to excellent selectivities, acceleration reaction rate in some cases, ease of work-up, as well as recycling use after simply recoveration. The esterification reaction widely used anic synthesis and other fields, and its technology is also in the continuous development. The classification, synthesis, and applications research of the ionic liquids are introduced in brief, its applications in esterification as catalysts are summarized in this paper, and prospected its future development.
