Abstract
La présente invention a pour objet un procédé pour effectuer 1'éthylation d'un mono alkyle benzène en un mélange d'éthyltoluène ou de diéthylbenzène. Elle est caractérisée en ce que l'on met ce mono éthyl alkyl benzène au contact d'un agent d'éthylation dans des conditions convenables pour la conversion, en présence d'un catalyseur comprenant une zéolite de type alumino-silicate ayant un indice de contrainte compris entre 1 et 12 et un rapport silice/ alumine supérieur à environ 500. Elle se rapporte à la production d'éthyltoluène ou de diéthylbenzène ne renfermant que des traces de produits secondaires indésirables.
