中文摘要：

合成了一种新型的酸性离子液体催化剂——复合离子液体，该离子液体的阴离子具有双金属的配位中心。同时，研究了复合离子液体催化异丁烷与丁烯烷基化反应的规律。结果表明，在搅拌速率大于1500r／min，反应低于20℃，烃酸比2：1～3：1，烷烯比大于15，反应停留5min～10min，使用丁烯-2为碳四烯烃反应原料下，复合离子液体催化碳四烷基化所得烷基化油的研究法辛烷值（RON）最高可达100以上，明显优于常规氯铝酸离子液体催化所得烷基化油的质量。

英文摘要：

A novel ionic liquid （IL）, composite IL, which contained enough quantity of multi-center ligand, AlCl4 CuCl^ -, was successfully synthesized. The effects of reaction temperature, reaction time, stirring speed and isoparaffin/olefine （I/O） ratio on the composite-IL-catalyzed alkylation were studied. The results showed that the research octane number （RON） of the yielded alkylate gasoline can be higher than 100 under the optimal conditions： stirring speed 〉 1 500 r/min, reaction temperature 〈 20℃, I/O ratio 〉 15 and reaction time in range of 5 min to 10 min. The multi-center ligand, AlCl4CuCl^- , should be accounted for the super selectivity of trimethylpentane （TMP） of isobutane alkylation catalyzed by composite IL.
