Al-bentonite, Friedel–Crafts alkylation, benzyl chloride, p-xyleneAbstract
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 nOH-/nAl3+ 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.
