Abstract

 A series of new imidazolium-type ionic liquids based on polyethylene glycol have been prepared. The new recyclable temperature-dependant phase-separation system comprised of [C12minPEG800] Br and methylcyclohexane was also developed and successfully applied to the DICHLOROMETHYLATION of some AROMATIC HYDROCARBONS to prepare dichloromethyl-substituted hydrocarbons in excellent yields. The ionic liquid could be excellent recycled without any apparent loss of catalytic activity and little loss of weight even after 8 times recycling.
