研究了少量 HCl调变的氯铝酸室温离子液体超强酸催化体系中 ,苯与碳 - 12烯以及氯甲烷的烷基化反应 .对于前一反应 ,以溶有 HCl的氯铝酸室温离子液体为催化剂与没有 HCl的相比 ,反应的产物分布不同 ;而后一反应过程中有 HCl生成 ,与纯 Al Cl3 作催化剂相比 ,催化活性显著提高 .实验结果还表明 ,生成的烷基化产物不溶于离子液体 ,因而易于分离 ,催化剂可以重复使用 The alkylation reaction of benzene with carbon-12 alkene and methyl chloride in a few HCl-modified room temperature ionic liquid superacid catalysts was studied. For the previous reaction, As the catalyst compared with the absence of HCl, the product distribution of the reaction is different; and after a reaction with HCl generated, compared with pure AlCl3 as a catalyst, the catalytic activity was significantly increased.Experimental results also show that the resulting alkylated product insoluble In ionic liquids, and therefore easy to separate, the catalyst can be reused
