The selectively catalytic gas phase flow reaction of benzene and propene over the catalysts was tested. The result show that the SO 2-4/ZrO2-MCM-41(SZM-41) can be used as a catalyst for the title reaction and has a high catalytic activity under some conditions.展开更多

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.展开更多
