When the mol quantity of Cu2+ dissolved was 5% of those of AlCl3 in ionic liquids, alkylation results from ionic liquids is comparable with those obtained with concentrated sulfur acid: the yield of alkylate reaching 178% of the volume of butene inputted, the selectivity of C8 reaching 75% and the octane number of alkylate reaching 92.2.

溶入Cu2+和Cu+后，离子液体的催化性能有显著的改善，当Cu2+的摩尔加入量为三氯化铝的5%时，烷基化油收率达到丁烯体积的178%，对C8的选择性为75%，烷基化油辛烷值为92.2，并且离子液体可以重复使用。
