Title (EN) PRODUCTION OF PARA-XYLENE
(FR) PRODUCTION DE PARA-XYLÈNE
Abstract:
(EN) The invention is a process for producing paraxylene, benzene and/or toluene is alkylated with methanol in the presence of a catalyst under conditions effective to convert said benzene and/or toluene to xylene and produce a product stream containing water, xylene and one or more phenolic impurities. The said product stream is separated into a water-rich stream and a xylene-rich stream containing one or more phenolic impurities and at least a portion of the xylene-rich stream is contacted with an aqueous solution of a base under conditions to remove at least some of the phenolic impurities from the xylene-rich stream portion.
(FR) L'invention concerne un procédé de production de paraxylène, suivant lequel du benzène et/ou du toluène sont alkylés par du méthanol en présence d'un catalyseur dans des conditions efficaces pour convertir ledit benzène et/ou toluène en xylène et donner un courant de produit contenant de l'eau, du xylène et une ou plusieurs impuretés phénoliques. Ledit courant de produit est séparé en un courant riche en eau et un courant riche en xylène contenant une ou plusieurs impuretés phénoliques et au moins une partie du courant riche en xylène est mise en contact avec une solution aqueuse d'une base dans des conditions pour retirer au moins une partie des impuretés phénoliques de la partie de courant riche en xylène.
