The benzylation of xylenes using heterogeneous catalysts from rice husk ash silica modified with gallium, indium and iron
F Adam, AE Ahmed - Chemical Engineering Journal, 2008 - Elsevier
Rice husk ash (RHA) was used to synthesize RHA-Ga, RHA-In and RHA-Fe catalysts by
direct incorporation of the respective ions into rice husk ash silica at room temperature. The
prepared catalysts were used to catalyze the benzylation of p-xylene (p-Xyl) with benzyl
chloride (BC). The catalysts had a BET specific surface area of ca. 272–347m2g− 1. The
catalytic activity increased with a decrease in the p-Xyl/BC molar ratio. However, the
selectivity towards the mono-benzylated product decreased. RHA-Fe showed the highest …
