| Abstract: | 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. The experiments show that all these chloroaluminate ionic liquids have good catalytic activity, and the highest monoalkylation selectivity of the reaction reaches 98.1% in Et_3NHCl-AlCl_3 ionic liquid. The catalysts are easy to be separated by simple decantation and can be recycled without obvious loss. |
