| description | This disclosure provides an improved process for converting benzene/toluene via methylation with methanol/dimethyl ether for producing, e.g., p-xylene, comprising separating and recycling dimethyl ether from the methylation reaction product mixture effluent to the methylation reactor. High selectivity toward p-xylene, among others, can be achieved.
La présente invention concerne un procédé amélioré de conversion de benzène/toluène par méthylation avec du méthanol/éther diméthylique pour produire, par exemple, du p-xylène, comprenant la séparation et le recyclage de l'éther diméthylique de l'effluent de mélange de produit de réaction de méthylation au réacteur de méthylation. Une sélectivité élevée vis-à-vis du p-xylène, entre autres, peut être obtenue. |
