Alkylation of benzene with propene over SO42-/ZrO2 catalyst

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 N-2 gas at 4.0 MPa. The reactants were pumped into the quantifier where the pressure was maintained by N-2 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 he used as a catalyst for the tide 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.
