A method is provided for preparing a para-selective, zeolite-based aromatics alkylation catalyst by treating a ZSM-5 type zeolite base catalyst composite with an aqueous magnesium nitrate solution and thereafter calcining the composite so treated. Such catalysts can be used in alkylation processes to provide alkylated aromatic product mixtures having exceptionally high concentrations of the para-dialkylbenzene isomer. |
