离子液体Et 3 NHCl-2AlCl 3对正戊烷异构化反应具有催化作用。在高压釜中考察了离子液体与几种产物分布改进剂对正戊烷异构化反应的催化性能。苯、环己烷、甲基环己烷等改进剂可以改善正戊烷异构化的产物分布，但会降低正戊烷的转化率。确定了最佳的产物分布改进剂为环己烷。随着环己烷用量的增加，异构化产物的产率和液体异构烷烃的选择性增加，而正戊烷的转化率降低。在正戊烷转化率相同的情况下，环己烷加入量为0.5wt%时，液体产物的研究法辛烷值（罗恩）比不加入环己烷时高1.3左右。在相同的反应条件下，环己烷的存在提高了异构体的产率、液体异构烷烃的选择性和液体产物的罗恩值，但降低了正戊烷的转化率。
The ionic liquid Et3NHCl-2AlCl3can catalyze the isomerization of n-pentane. This paper investigates the ionic liquid catalyzed isomerization performance of n-pentane with several product distribution improvers in an autoclave. The product distribution of n-pentane isomerization could be improved by such improvers as benzene, cyclohexane, and methyl cyclohexane at the expense of conversion of n-pentane. The optimal product distribution improver was determined to be cyclohexane. The yield of isomerate and the selectivity of liquid isoalkanes increased, whereas the conversion of n-pentane decreased, with increasing cyclohexane amount. At the same conversion of n-pentane, the research octane number (RON) of liquid product, with cyclohexane amount of 0.5 wt%, was about 1.3 higher than that without cyclohexane. At the same reaction conditions, the presence of cyclohexane enhanced the yield of isomerate, the selectivity of liquid isoalkanes, and the RON of the liquid product, but reduced the conversion of n-pentane.
