✦ Synopsis

Zeolites H-BEA, H-FAU and Na®on/silica composites show high activity in the acylation of anisole with octanoic acid. A study of activity, surface area characteristics and acidity of zeolite H-BEA shows that mesoporosity and the Si/ Al ratio are very important features for activity. Coating a monolithic carrier by a convenient coating procedure with BEA results in an active and selective integrated catalyst-reactor con®guration for the acylation of aromatics. Due to the binding capacity of the silica binder a mechanically stable coating layer was obtained.
