摘要：
1-Butyl-3-methylimidazolium bromochloroaluminate([bmim]Br-AlCl) ionic liquid was used as an acid catalyst for removal of trace olefins from the aromatic hydrocarbons.The influence of various reaction parameters such as reaction time,temperature,dosage and acid strength of catalyst was investigated.The experimental results demonstrated that the ionic liquid exhibited excellent activity under mild reaction conditions,with the conversion of olefins reaching 98.84%and the bromine index of the aromatics varying from 1129 to 13.On the basis of the results obtained,thereof,a possible reaction mechanism was proposed.
