| 摘 要： | HX is immobilized by reaction of halogen acid with methylimidazole, and the formed ionic liquid Hmim]X was used as halogenating agent, catalyst as well as medium for conversion of alcohols to alkyl halides. Excellent yields were obtained. The halides produced could be easily separated from the reaction mixture via simple decantation, and the ionic liquid Hmim]X could be regenerated conveniently by adding equivalent of halogen acids followed by removal of water.
