Process for the alkylation of aromatic compounds by the re-actionnof the aromatic compound of interest with isopropanol,nalone or mixed with propylene, characterized in thatnsaid reaction is carried out in the presence of a catalyticncomposition based on zeolite, under mixed gas-liquid phasenconditions or under completely liquid phase conditions, atnsuch temperature and pressures that the concentration ofnwater in the reaction liquid phase is not higher than 8,000nppm w/w, regardless of the total water content present innthe reaction mixture. |
