Catalysed alkylation of toluene with methanol on zeolites proceeds in two different ways, depending upon the nature of the zeolite, and gives rise to ethylbenzene-styrene and/or xylenes. The results indicate that the activity and selectivities are dictated by the acidity and electronegativity of the zeolites with the most electropositive ones producing ethylbenzene and styrene and the most electronegative catalysing formation of xylenes.

Abstract
Catalysed alkylation of toluene with methanol on zeolites proceeds in two different ways, depending upon the nature of the zeolite, and gives rise to ethylbenzene-styrene and/or xylenes. The results indicate that the activity and selectivities are dictated by the acidity and electronegativity of the zeolites with the most electropositive ones producing ethylbenzene and styrene and the most electronegative catalysing formation of xylenes.File in questo prodotto:
