Abstract: Applications of ionic liquids for Friedel-Crafts reactions are reviewed，in which ionic liquid can be functioned as a catalyst or a solvent. The advantages of ionic liquids are irreplaceable by any other catalysts or solvents. Problems encountered in the application of ionic liquids for Friedel-Crafts reactions are analyzed and prospects for future development are also discussed.

摘要： 对Friedel-Crafts反应和离子液体作了简要介绍，并重点介绍了离子液体在Friedel-Crafts酰基化及烷基化反应中的应用。在Friedel-Crafts反应中，离子液体既可以作为催化剂，也可以作为溶剂，具有其它催化剂或溶剂不可替代的优点。同时简要分析了离子液体应用所面临的问题并展望了其未来发展趋势。
