SHAPE SELECTIVE REACTIONS WITH ZEOLITE CATALYSTS MODIFIED WITH GROUP IA METALS

摘要

ABSTRACTA process for the conversion of aromatic compounds todialkylbenzene compounds rich in the 1,4-dialkylbenzene isomer. Thereaction is carried out in the presence of a particular type of zeolitecatalyst having a silica to alumina mole ratio of at least 12 and aconstraint index of about 1-12, said catalyst having been modified bytreatment with metal compounds of elements from Group IA of the PeriodicChart, and optionally phosphorus, to deposit a minor proportion of suchelements on the zeolite.
