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.

伯醇除某些低沸点底物外，都以高转化率(最高达100％)和高选择性(最高达100％)转化为相应的氯代烃、溴代烃和碘代烃，例如正辛醇、苯甲醇，在X中进行卤代反应得到令人满意的结果，无论氯代、溴代还是碘代得到卤代产物的收率一般都很好华东师范大学化学系01级博士学位论文(95十100%)，极少有重排产物及脱水产物被检测出来。

Fe2O3 acts as an activator more than a catalyst in the desulfurization reaction with lime. Fe2O3 acts as the "activation center" around which CaO particles are sulfurized. The new dispersal formation mode of product differs from the compact layer that used to be. And the pore structure of product layer on the surface of lime particles is optimized, which makes SO2 penetrate into core parts of lime more easily. As a result, the desulfurization reaction is developed deeper into the core parts of absorbent.

氧化铁所起的是改变石灰颗粒表层产物生成方式的活化作用，使反应生成物不会形成一个致密的外壳，而以氧化铁为活性中心进行硫化反应，形成了分散的硫酸钙产物堆积，改善了硫化过程中的表面孔隙结构，减少了石灰颗粒表面硫化产物层对反应气体向石灰颗粒内部扩散的阻力。
