Özet:

 


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)) were characterized by
IR, SEM, XRF, and BET analyses. The catalytic activity of 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 styrene hydrogenation was
obtained with TOF value as 5871 h-1 at 370 K, 10 bar H2
and 1500 psi total pressure. Especially, while
homogeneous counterpart has not activity in cyclohexene hydrogenation, it has
been provided 100% cyclohexane conversion with the immobilized catalyst. It has also been found
that the catalyst can be reused at least ten times without significant loss of
activity in the styrene hydrogenation
