Prepation of phosphiie derivatives ligand and their metal complexes, investigation of their catalytic activity in styrene hydrogenation by using microemulsion technique

In this thesis,phosphine derivatives ligands which is known that not soluble in scCO2, was sulfonated to make them water soluble and Rhodium metal complexes were synthesized.structure of synthesized ligands and catalysts were characterized byspectroscopic methods such as FT-IR, 1H, and 31P NMR.Solubility measurements of catalysts were performed at the conditions of 70 oC temperature and 2700 psi CO2 pressure.Catalytic activity of catalysts in supercritical carbondioxide media were examined by using microemulsion technique on hydrogenation of styrene which was selected as a model compound styrene. Hydrogenation reactions of catalysts were performed at the different temperature and pressure and we found that the best conversion was determined under 80 oC ve 150 psi H2 ve 4000 psi (PCO2+PH2) total pressure values
