摘要：

The catalytic activity of commercial niobium phosphate was evaluated in the benzylation of aromatic compounds with benzyl alcohol, in liquid phase. The conversion of benzyl alcohol was 100% in the reactions with toluene, ethylbenzene, propylbenzene and p-xylene while the highest selectivity in monobenzyl derived compounds (91%) was achieved with p-xylene. The formation of dibenzyl ether was also observed, indicating the presence of Bronsted acids sites in this type of catalyst. (C) 2002 Elsevier Science B.V. All rights reserved.
