Popis:	article i nfo Acidity Alkylation Aromatics l-Alkenes The liquid-phase alkylation of benzene with 1-tetradecene was realized over dealuminated mordenites with dif- ferent mesoporous surface areas and three different levels of acidity. The mordenite catalysts were characterized by N2-sorption, FTIR pyridine adsorption, and TPDA. The number of Bronsted acid sites decreases; however, it represents a higher proportion of the total acidity. Alkylation results demonstrated that the mordenite activity in alkylation accelerated with increasing mesoporous surface area in spite of the lower total acidity. This fact in- dicatesthat the accessibility of acid sites and the internal mass transport inmordenite channels play a significant role in liquid-phase alkylation of aromatics with 1-alkenes.
