Alkylation of benzene with 1-hexene in chloroaluminate ionic liquids with Lewis acidity was investigated. The ionic liquids acting as catalysts were prepared from emimBr, bmimBr, Et_3NHCl, C_4H_9NBr,C_ 19H_ 42BrN and aluminium chloride.

• 以溴化 1 -乙基 - 3 -甲基咪唑 (emim Br) ,溴化 1 -丁基 - 3 -甲基咪唑 (bmim Br) ,盐酸三乙胺 (Et3NHCl) ,溴化四丁基铵 (C4 H9NBr) ,十六烷基三甲基溴化铵 (C19H4 2 Br N)分别与 Al Cl3原位合成法制备离子液体催化体系。
