The conversion of alcohols to alkyl halides was investigated using acidic ionic liquid X as halogenating agent, acidic catalyst as well as medium.

2以酸性离子液体X兼作卤代试剂、反应介质和酸性催化剂，研究了醇转化为卤代烃的反应。

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.
