The toluene conversion, the selectivity to styrene and ethylbenzene (C₈ selectivity) in the oxidative methylation of toluene with methane have been studied comparatively for the KY zeolite catalyst promoted with Li₂O, Na₂O, K₂O, and Cs₂O respectively. It was found that the effect of promoter decreased in the order:Cs₂O > Na₂O > Li₂O > K₂O.
