ABSTRACT:
A zeolite catalyst composition suitable for para-selective conversion of substituted aromatic compounds, e.g., conversion of aromatic compounds to dialkylbenzene compounds rich in the 1,4-dialkylbenzene isomer. Such a composition comprises a zeolite catalyst component having a silica to alumina mole ratio of at least 12 and a constraint index of about 1 to 12, and a minor amount, e.g., at least 0.5 weight percent of a Group IIIA element, e.g., scandium, yttrium or Rare Earth elements, and optionally phosphorus, said elements being present in the form of their oxides.
