The conversion of alcohols to alkyl halides was investigated using acidic ionic liquid X as halogenating agent, acidic catalyst as well as medium. The reactions of primary alcohols gave very satisfactory conversions and selectivities except for the substrates with lower boiling point,such as n-octanol and benzyl alcohol. They obtained the corresponding halides with almost quantitative yields(95%-100%).The secondary alcohols also gave the corresponding halides with excellent conversions, however, the by-products of dehydration were detected.
