| 摘 要： | 水热合成了介孔材料SBA-15，并以其为载体负载固体超强酸SO42－/ZrO2，得到催化剂
SO42－/ZrO2/SBA-15，通过XRD对其进行表征。在固定床反应器中，以丙烯和乙酸为原料，研究该催化剂催化合成乙酸异丙酯的活性。对反应条件进行系统地考察，得出最佳反应条件：反应温度140 ℃,反应压力1.2 MPa,空速1 h－1,n(C3H6)∶n(CH3COOH)=3∶1。在此条件下乙酸异丙酯的产率最高可达79.6％。

| Abstract: | Solid superacid SO42－/ZrO2 was supported on surface of SBA 15 prepared by hydrothermal method. The SO42－/ZrO2/SBA 15 catalyst was characterized by XRD technique. Catalytic activity of SO42－/ZrO2/SBA 15 for synthesis of isopropyl acetate from propylene and acetic acid was studied in a fixed bed reaction system, including the reaction condition. Optimum reaction condition was obtained as follows: reaction temperature 140 ℃, reaction pressure 1.2 MPa, space velocity (LHSV) 1 h－1, n(C3H6)∶n(CH3COOH)=3∶1. Isopropyl acetate yield of up to 79.6% was obtained under the optimum condition. |
