Abstract
Viene descritto un procedimento per la isomerizzazione di composti diclorurati aromatici nel quale detti composti diclorurati aromatici vengono posti a contatto, in fase liquida ed in condizioni di reazione, con un catalizzatore solido ottenuto per scambio tra la forma acida di una zeolite ZMS-5 ed un sale di un metallo alcalino, alcalino-terroso, del terzo gruppo o di transizione.
