Abstract
Procedeul de etilare selectiva a toluenului sau a etilbenzenului folosind etilena ca agent de etilare, rectia avînd loc la temperatura de 250...600 degree C, la presiunea de 0,1...100 at, cu o viteza spatiala orara masica cuprinsa între 0,1 si 10, de preferinta 2,5 si 7,5 si folosind un catalizator pe baza de aluminosilicati cristalini al carui indice de constructii este cuprins între 1 si 12, consta în aceea ca reactia de etilare are loc în prezenta hidrogenului, a azotului sau a amestecului acestora, cantitatea gaz diluant folosita în raport cu etilena variind între cea echimoleculara si raportul etilena/gaz diluant egal cu 1/3.
