摘　　要：将室温离子液体1-丁基-3-甲基咪唑氯铝酸盐通过浸渍法负载到无机多孔材料H-β沸石上制备负载化离子液体催化剂,研究结果表明当以二氯甲烷为分散剂,离子液体与沸石的配料比为1∶4,振荡时间为12h时负载率最大为66%;采用FT-IR、BET、SEM和XRD对催化剂进行表征。将负载沸石用于催化苯酐与乙苯发生F-C酰基化反应,并采用FT-IR、UV对产物进行分析,证明产物为2-(4-乙基苯甲酰基)苯甲酸(BEA)。Immobilized ionic liquid catalyst was prepared by impregnation method which the ionic liquid 1-butyl-3- methyl imidazole chlorine atuminate was supported on an inorganic porous β-zeolite. The results showed that the maximum loading rate was 66% with dichloromethane as the dispersion solvent under conditions of amount ratio of ionic liquids and zeolite 1：4, reacting time 12h. Then the catalyst was characterized by FT IR,BET,SEM and XRD methods. Loaded zeolite catalyst was used for catalyzing F-C acylation reaction of phthalic anhydride and ethyl benzene. FT-IR, UV methods were used to analyze the product,and the reaction products was proved to be 2-（4-ethyl benzoyl） benzoic acid （BEA） during analysis of the product.
