Lv. Piryutko et al., SILYLATION EFFECT ON THE CATALYTIC PROPERTIES OF FEZSM-11 IN BENZENE OXIDATION TO PHENOL, Reaction kinetics and catalysis letters, 52(2), 1994, pp. 275-283
The outer surface of FeZSM-11 zeolite was selectively silylated withou
t affecting the inner system of its channels. SiO2 deposition suppress
ed both the acidity and catalytic activity of the outer surface in mes
itylene isomerization. Neither zeolite activity, nor its stability in
N2O benzene oxidation to phenol have changed upon silylation, This fac
t gives evidence that the latter reaction proceeds primarily within th
e zeolite channels.
