Abstract

To control the styrene to ethylbenzene ratio in the products of side-chain alkylation of toluene with methanol over Cs-X-based catalysts, pathway to ethylbenzene was examined. Styrene underwent transfer hydrogenation with methanol much faster than hydrogenation with hydrogen to ethylbenzene. Addition of Cs₂O and ZrB₂O₅ to Cs-X enhanced and suppressed, respectively, the transfer hydrogenation.
