摘要
Alkylation of benzene with alkene and/or chloroethane in Lewis acid-typeionic liquid catalysts, MEIC + AlCl3, MBIC + AlCl3, BPC + AlCl3 and TMHC + AlCl3, which in situ were prepared by the reaction of 1-methyl-3-ethylinidazole chloride (MEIC), 1-methyl-3-butylinidazole chloride (MBIC), 1-butylpyridium chloride(BPC) and trimethylarnine hydrochloride (TMHC) with AlCl3 respectively, at room temperature has been investigated. The experimental result shows that the ionic liquid catalysts have higher catalytic activity than that of peer AlCl3. The conversion can reach 100% in shorter time and the selectivity of TMHC-AlCl3 for monoalkylation of benzene can get 98.6%. In addition, the products are easily separated and the ionic liquid catalysts can be reused in the reaction.
