ABSTRACT:
Mononuclear aromatic hydrocarbons such as benzene and toluene are alkylated with C.sub.2 -C.sub.4 paraffins in the presence of an acidic zeolite catalyst such as ZSM-5 in a one-step process to produce alkylaromatic products in high selectivity. Benzene and propane reactants produce predominantly C.sub.7 to C.sub.9 aromatics.
