Abstract

L'invention concerne un processus destiné à la préparation d'éthylbenzène par alkylation en phase liquide et transalkylation en phase vapeur. La réaction d'alkylation en phase liquide peut être catalysée par un oxyde solide acide, tel que le MCM-22, le MCM-49, le MCM-56. La réaction de transalkylation en phase vapeur peut être catalysée par du zéolite de dimension de pores moyenne tel que le ZSM-5. On peut exécuter ce processus en continu en ajoutant de manière continuelle un apport de benzène frais contenant au minimum 500 mg/l d'impuretés d'hydrocarbures non benzéniques. Le produit combiné d'éthylbenzène obtenu par ces réactions d'alkylation et de transalkylation possède très peu d'impuretés, constituées de xylène, d'hydrocarbures à 7 atomes de carbone ou moins et d'hydrocarbures à 9 atomes de carbone ou moins.
