摘要
Methylation of different methylbenzenes on a zeotype acid catalyst has been investigated through quantum chemical calculations on a cluster model. The activation energy for methylation decreases as the number of methyl groups already in place on the benzene increases. Implications for the mechanism of the methanol-to-hydrocarbon (MTH) reaction are discussed.
