| 摘 要： | 用浸渍法将SO4^2-／ZrO2引入到MCM-41中，用XRD、IR、Py-IR等技术对其进行表征，并考察了制备条件对苯与丙烯气相流动反应的催化活性影响。结果表明，适宜的制备条件可制得对苯与丙烯烷基化反应有良好催化活性的SO4^2／ZrO2-MCM-41催化剂。

| Abstract: | Super acidic Catalyst SO 4 2- /ZrO 2 were introduced int o pure silicone MCM-41 by macerating method and characterized by XRD, IR, and Py-I R. Effect of the preparative condition on catalytic synthesis of iso-propyl benz ene in the catalysts has been tested. The result shows that the catalyst shows h igher conversion for the propene and higher selectivity for the iso-propyl benze ne when the SO 4 2- /ZrO 2-MCM-41 was prepared in some condition. |
