Abstract

La présente invention a pour objet un procédé pour la conversion sélective de monoalkylbenzènes en para-dialkykbenzènes en présence d'un catalyseur consistant en une zéolite à base d'aluminosilicates cristallins. cette zéolite est caractérisée par une activité, exprimée en termes de valeur alpha, comprise entre 2 et 5000, par une capacité de sorption de xylene supérieure à 1 g/100 g de zéolite et par une durée de sorption de l'orthoxylène pour 30 % de cette capacité supérieure à 10 mn, lesdites capacités de sorption et la durée de sorption étant mesurées à 120 degrés C, ainsi que par une pression de xylène de 4,5 +- 0,8 mm de mercure, ladite zéolite à base d'aluminosilicate cristallin ayant un rapport silice/alumine d'au moins 12 et un indice de contrainte de l'ordre d'environ 1 à 12. Elle se rapporte à un procédé de production d'éthyltoluène ou de diéthylbenzène pratiquement exempt de l'isomere ortho indésirable et qui élimine les coûteuses etapes de purification nécessaires jusqu'à présent.
