ABSTRACT:
A zeolite catalyst composition suitable for para-selective conversion of substituted aromatic compounds, e.g., to dialkylbenzene compounds rich in the 1,4-dialkylbenzene isomer. Such a composition comprises a zeolite catalyst having a silica to alumina mole ratio of at least 12 and a constraint index of about 1-12, and a minor amount, e.g., at least 0.25 weight percent of one or more of the alkaline-earth metals (Ca, Sr, Ba), and optionally phosphorus.
