A series of catalysts was prepared for the liquid-phase Friedel–Crafts benzylation of toluene with benzyl chloride (BC) by impregnating rice husk ash silica with ZnCl2 (3 wt%, 6 wt%, 9 wt%, and 12 wt%) via a wet impregnation method. The XRD analysis indicates that the catalysts were amorphous with...
