Abstract

Abstract: Super acid catalyst SO₄^2-/ZrO₂ was introduced into pure silicone MCM-41 via the impregnation method and the catalyst samples obtained at different temperatures were characterized by means of XRD, IR, and Py-IR techniques.The selectively catalytic gas-phase flow reactions of benzene with propene over the catalyst samples were carried out in a made-to-measure high-pressure flow reactor equipped with a thermostat and a condenser. Effect of the preparative condition on the catalytic synthesis of isopropyl benzene over the catalyst samples was tested. The results show that SO₄^2-/ZrO₂-MCM-41 (SZM-41) can be used as a catalyst for the title reaction, in which there are a higher conversion (97%) for the propene and a higher selectivity(93%) for the isopropyl benzene.

Key words: Benzene, Propene, Isopropyl benzene, SO₄^2-/ZrO₂-MCM-41 catalyst
