Abstract
Described are catalyst compositions comprising a high surface area, zinc-modified, crystalline silica molecular sieve, essentially free of aluminum, which has been incorporated into an inorganic matrix; said compositions are useful for hydrocarbon conversion, particularly the propylation of toluene in which they exhibit a very high paraselectivity while making a product containing a high isopropyltoluene/n-propyl-toluene isomer ratio. These catalyst compositions are made from an organic base, a templating material, a zinc ion-affording compound, and an oxide of silicon.
