The present invention relates to a catalyst composition. It is characterized in that it comprises a crystalline zeolite of aluminosilicate type having an alpha activity of 2 to 5,000, a xylene sorption capacity greater than 1 gram per 100 grams of zeolite and an ortho-xylene sorption time. for 30% of this capacity greater than 10 min, the time and the sorption capacity being measured at 120 degrees C under a pressure of 4.5 ± 0.8 mm of mercury. It relates to a process for the selective production of para-dialkyl substituted benzene and a catalyst suitable for this purpose. |
