Abstract

The reaction of benzyl alcohol and dibenzyl ether on several zeolites was studied in the temperature range 300–500 °C. The major products were benzaldehyde and toluene due to disproportionation, anthracene due to intermolecular alkylation followed by cyclodehydration, benzyltoluenes due to alkylation followed by hydrogenolysis, and stilbene. The alkylation course was strongly influenced by shape selectivity with the large pore zeolites mainly yielding anthracene and the medium pore zeolites benzyltoluene. The formation of stilbene was a new observation which has a bearing on the mechanism of the methanol-to-hydrocarbon reactions.
