CAS  The adsorbed oxygen on Pd surface plays the important role that can activate the CH bond of CH3 group in acetophenone, leading to the formation of a new intermediate (perhaps acetophenone enolate). Enhanced selectivity and formation of ethylbenzene for acetophenone hydrogenation by adsorbed oxygen on Pd/SiO. We use cookies to help provide and enhance our service and tailor content and ads. The conversion of ethylbenzene is more than 90% and the selectivity of acetophenone is more than 95% at 353 K. Graphene can be used as catalyst owing to its unique structures and chemical properties.

This intermediate is the key species that will be further hydrogenated to ethylbenzene. The selectivity of ethylbenzene can be significantly boosted to over 90%, even if the reaction approaches zero conversion, suggesting that phenylethanol needs not be an intermediate for production of ethylbenzene from acetophenone.
