α-Alkyl benzoic alcohol is hydrogenated over Pd/C in the H2-HAc-HClO4 system into the corresponding branched-alkyl benzene.The influence of the reaction temperature
hydrogen gas pressure and the amount of catalyst is investigated.Perchloric acid as co-catalyst plays a key role in relation to the catalyst activity.Room temperature (15—30℃)
H2 pressure (400—800 kPa)
and 5%—10% Pd/C catalyst by mass are the optimum conditions for this hydrogenation reaction.Perchloric acid as co-catalyst can lead to formation of PdOxCly cluster on the surface of Pd during the hydrogenation reaction.PdOxCly cluster may be a new active center
