Abstract

Pd(II) complex containing S,O-chelating ligand was immobilized on surface of the amine functionalized silica support in $scCO2$media. Silica-based catalyst ($SiO2$-ThiophPd(II)) was characterized by IR, SEM, XRF, and BET analyses. The catalytic activityof the immobilized catalyst in hydrogenation reactions of alkenes has been compared with the homogeneous counterpart. $SiO2$-ThiophPd(II) catalyst showed good activity and reusability than homogeneous system. The best conversion in styrenehydrogenation was obtained with TOF value as 5871 h-1 at 370 K, 10 bar H2 and 1500 psi total pressure. Especially, whilehomogeneous counterpart has not activity in cyclohexene hydrogenation, it has been provided 100% cyclohexane conversionwith the immobilized catalyst. It has also been found that the catalyst can be reused at least ten times without significant lossof activity in the styrene hydrogenation.
