| 摘 要： | 用水热合成法合成了一种新型的复合型固体超强酸SO42－/ZrO2/MCM-41催化剂，并通过IR和XRD方法进行了表征。在固定床反应器中，以苯乙烯和二甲苯为原料，对该催化剂催化合成二芳基乙烷的反应进行了研究，确定最佳反应条件：苯乙烯与二甲苯混合进料物质的量比为1∶4，反应温度75 ℃，空速1 h－1。在此条件下，苯乙烯单程转化率可达93.5%，二芳基乙烷的选择性为78.9%。表明该催化剂是替代液体酸合成二芳基乙烷的理想固体酸催化剂。

| Abstract: | A novel solid superacid SO42-/ZrO2/MCM-41 catalyst was prepared by hydrothermal method and characterized by infrared spectroscopy (IR) and X ray diffraction (XRD) techniques. Catalytic synthesis of diphenylethane from styrene and xylene was studied on a fixed bed reactor system using the catalyst. Optimum reaction condition was obtained as follows:n(styrene)∶n(xylene)=1∶4, reaction temperature 75 ℃; LHSV 1 h－1. Styrene conversion of 93.5% and selectivity to diphenylethylane of 78.9% were attained under the optimum condition. The results showed that SO42-/ZrO2/MCM-41 is a promising solid acid catalyst for synthesis of diphenylethylane instead of liquid acid. |
