Abstract
Polymer bound Pd(II) complexes have been synthesised by sequential attachment of ethylenediaminetetraacetic acid (EDTA) ligand to chloromethylated styrene-divinyl benzene copolymer and treatment with palladium salt. The prepared catalysts were characterized by various techniques such as UV-Vis reflectance spectroscopy, IR, ESR, SEM and TG analysis. Various physico-chemical properties such as surface area (by BET method), moisture content, bulk density and swelling by different solvents have also been studied. Catalytic activity of these catalysts was tested for hydrogenation of 1-hexene as a model reaction. The influence on the rate of variation in temperature, concentration of the catalysts as well as the substrate and nature of solvent was studied. Entropy of activation was calculated from the kinetic data. The recycling efficiency of the catalysts was also studied. A probable reaction mechanism has been proposed.
