| 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。

| Abstract: | A novel ionic liquid (IL), composite IL, which contained enough quantity of multi-center ligand, AlCl4CuCl－, 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 > 1500r/min, reaction temperature < 20℃, I/O ratio >15 and reaction time in range of 5min to 10min. The multi-center ligand, AlCl4CuCl－, should be accounted for the super selectivity of trimethylpentane (TMP) of isobutane alkylation catalyzed by composite IL. |
