Abstract:
Super acidic catalyst SO42-/ZrO2 was prepared and characterized by XRD,IR,and Py-IR. Selectively catalytic gas phase flow reactions of benzene and propene over the catalyst were carried out in a made-to-measure high pressure flow reactor with a thermometer and a condenser. The benzene and propene were kept in pressure tanks at 8 : 1 ratio with N2 gas at 4. 0 MPa. The reactants were pumped into the quantifier where the pressure was maintained by N2 gas at 8. 0 MPa. They were then pumped into the reaction reactor using catalytic synthesis of isopropyl benzene. The collected liquid phase products were analyzed using GC-MS. Product analyses were carried out on SE-54. The effect of the preparative condition on the catalytic synthesis of isopropyl benzene over the catalysts has been tested. The result shows that the SO42-/ZrO2 can be used as a catalyst for the title reaction,and shows higher conversion(99.2%)for the propene and higher selectivity(93.3%)for the isopropyl benzene when the catalyst is preparated in some condition.

摘要:
制备了SO42-/ZrO2催化剂并采用X射线衍射、红外光谱仪测定、Py-IR测定等技术对其进行了表征.反应在自制高压流动床(具有控温和冷凝)装置上进行,原料以苯: 丙烯为8: 1的比例配置于贮罐中,4.0 MPa N2恒压,压入计量器后,用8.0 MPa N2恒压. 反应后收集的液相产物由气相色谱-质谱(GC-MS)分析,产物分析在SE-54型毛细管色谱议上进行. 考察了苯与丙烯气相流动烷基化反应以及制备条件对催化活性的影响,结果表明,适当条件下制得的SO42-/ZrO2催化剂可用于合成异丙苯反应,并有高的丙烷转化率(99.2%)和高的异丙苯选择性(93.3%).
