Abstract

La présente invention a pour objet un procédé de préparation sélective de dérivés du benzène substitués en para par des groupes méthyle et/ou éthyle. Elle est caractérisée en ce qu'on fait réagir le toluène ou l'éthyl-benzène avec un agent de méthylation ou d'éthylation, à une température comprise entre 300 et 700 degrés C, en présence d'un catalyseur constitué d'un alumino-silicate cristallin zéolitique, à savoir, la zéolite ZSM-23. Elle se rapporte à la préparation sélective de benzène substitué en para.The present invention relates to a process for the selective preparation of benzene derivatives substituted in para by methyl and / or ethyl groups. It is characterized in that toluene or ethyl-benzene is reacted with a methylation or ethylation agent, at a temperature between 300 and 700 degrees C, in the presence of a catalyst consisting of an alumino -Zeolite crystalline silicate, namely, zeolite ZSM-23. It relates to the selective preparation of para-substituted benzene.
