Hydrogenation of 1-hexene using polymer supported Pd(II) complex catalyst

Polymer supported Pd(II) complex catalyst was synthesised by chloromethylation of styrene-divinylbenzene copolymer (XAD-2), with sequential attachment of ethylenediamine and salicylaldehyde, followed by treatment with an ethanolic solution of palladium chloride. The synthesised catalyst, named 2PS, was characterised by various techniques, such as UV-vis reflectance spectroscopy, IR, SEM, TGA and ESR. Other physico-chemical properties, such as surface area (by the BET method), moisture content, bulk density and swelling by different solvents, have been studied. The catalytic activity of the catalyst was investigated for hydrogenation of 1-hexene by varying different parameters, such as temperature, amount of the catalyst and concentration of 1-hexene.
