Abstract

In the present work, the benzylation of aromatics by benzyl chloride using Al-bentonite as a catalyst was investigated. Al-bentonite material showed both high conversation and high selectivity for the alkylation of aromatics. The present study investigated the  influence  of  different  parameters  such  as the ratio of n_OH^-/n_Al³⁺ in Al-bentonite synthesis,  the  amount of  the  catalyst, and temperature affecting  the  activity  of  the  catalyst  on  the benzylation  of  p-xylene was  reported. The kinetics of the p-xylene benzylation over this catalyst was demonstrated. The activation energy for the p-xylene benzylation over Al-bentonite was determined 136,62 kJ/mol.
