ABSTRACT:
A process for the conversion of aromatic compounds to dialkylbenzene compounds rich in the 1,4-dialkylbenzene isomer. The reaction is carried out in the presence of a particular type of zeolite catalyst having a silica to alumina mole ratio of at least 12 and a constraint index of about 1-12, said catalyst having been modified by treatment with compounds of manganese and/or rhenium, and optionally phosphorus, to deposit a minor proportion of such elements on the zeolite.
