Optimization of Process Parameters for Isopropylation of Toluene over Modified Zeolite using Response Surface Methodology
Abstract: Vapor-phase isopropylation of toluene with isopropanol has been investigated in a fixed-bed flow reactor under atmospheric pressure using N2 carrier gas over Cerium modified 13X zeolite catalyst. The main product of this alkylation reaction was p-cymene followed by meta-isomer, while ortho-cymene was negligibly formed. Response surface methodology was used to study the combined effects of temperature, reactant molar ratio and space time on the conversion of toluene and selectivity of …
