Methanol, in the presence of toluene, was completely converted to hydrocarbons above 400 C. However, depending on the ratio of toluene to methanol in the feed mixture and the reaction severity, only a fraction of the methanol participated in the toluene alkylation reaction, with the remainder being converted to gaseous hydrocarbons. Alkylation is found to be ortho/para-directing over the small-crystal ZSM-5, similar to that found with aluminum chloride and amorphous silica/alumina catalysts, whereas the large crystals showed high para selectivity. The catalytic results are shown to be consistent with the diffusion characteristics of the zeolite.
