Methylation of Toluene with Methane over ZSM-5 Catalysts

The methylation of toluene with methane in the presence of oxygen over zeolite catalysts is shown to be complicated by extensive disproportionation, hydrodealkylation, and hydrocracking reactions. However, it appears that these undesired reactions can be minimized, to enhance the methylation reactio...

Description
Summary:The methylation of toluene with methane in the presence of oxygen over zeolite catalysts is shown to be complicated by extensive disproportionation, hydrodealkylation, and hydrocracking reactions. However, it appears that these undesired reactions can be minimized, to enhance the methylation reaction, by using zeolites with reduced Brönsted acidity.
