摘　　要：The alkylation of p-cresol with tert-butanol（TBA）to 2-tert-butyl-p-cresol（TBC）catalyzed by a novel multiple-SO3H functioned ionic liquid（IL1）was investigated.Meanwhile,the catalytic activity of this novel ionic liquid was compared with other four traditional ionic liquids.The results showed that IL1 has superior catalytic activity to other four traditional ionic liquids with the conversion of 85.3%and selectivity of 95.2%.Also,the reaction conditions were investigated to obtain the optimum conditions.Operational simplicity,small amount of usage,high activity,reusability and selectivity are the key features of this methodology.有到新奇 multiple-SO3H 催化的 2-tert-butyl-p-cresol (TBC ) 的 tert-butanol (TBA ) 的 p 甲酚的完化工作了离子的液体(IL1 ) 被调查。同时，这新奇离子的液体的催化活动与另外的四传统的离子的液体相比。结果证明 IL1 与 85.3% 的变换和 95.2% 的选择举办优异催化活动到另外的四传统的离子的液体。另外，反应条件被调查获得最佳条件。运作的简洁，用法的小数量，高活动，可重用性和选择是这方法论的特色。
