英文摘要: The diphenyl oxide alkylation with dodecene catalyzed by acidic ionic liquids has been studied. The reuse potential of acidic ionic liquids has been investigated. The reasons for the deactivation of the acidic ionic liquids are the decomposition and leaching of the actual catalytic species Al2Cl7- from the interaction between acidic ionic liquids and diphenyl oxide. The interaction between acidic ionic liquids and diphenyl oxide couldn't be avoided by changing the cations of ionic liquids. The reuse problem of acidic ionic liquids can be solved when certain amount of AlCl3 is added into the used ionic liquids. The yield of target product is still around 90% after 8 cycles of the ionic liquids.
