Results showed that using aluminum trichloride combined catalyst under the conditions of a catalyst dosage of 5%, a benzene/olefin molar ratio of 8, a reaction temperature of 60℃ and a reaction time of 6 h, the yield of alky-benzene reached 19.6% and the quality of the obtained alkylate was significantly improved as compared with coker gas oil.

结果表明，采用三氯化铝复合催化剂，在催化剂质量分数为5%、反应温度60℃、苯烯摩尔比为8、反应时间6 h的条件下，烷基苯收率达到19.6％，烷基化油的质量明显优于焦化柴油。

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。

Nsted acid ionic liquids were inactive for the alkylation of isobutane with butene.In contrast,the chloroaluminate ioni c liquids were very active for the alkylation.However,the qualities of the alkylate oils using chloroaluminate ionic liquids were unsatisfied and worse than that of the products in the industrial sulfuric acid process obviously.

发现：所制备Bronsted酸离子液体无催化烷基化反应活性；而氯铝酸离子液体则具有很高的催化烷基化反应活性，但所得烷基化油质量较差，明显低于工业硫酸法水平。
