Abstract
To research chemical formation of the nitrogenous polymeric metal complex, this paper studies the catalysis of the polymeric metal complex in chemical reaction via the organic combination reaction. In this paper, a series of N-functionalized nitrogenous polystyrene ligands are prepared by making chloromethylate polystyrene resin (CPS) reacting with ethanol amine, 2-mercapto ethylamine (MEA), 8-hydroxyquinoline, anthranilic acid and imidogen oxalic acid (IDA) respectively, and crosslinked polyacrylamide is obtained by adopting solution polymerization and reversed phase suspension polymerization methods. Moreover, the polymeric metal complex is obtained by making nitrogenous polymer acting on the water solutions of FeCl3, 6H2O, CuCl2, 2H2O, CoCl2, 6H2O, NiCl2 and 6H2O at certain pH and temperature, the characteristics of nitrogenous polymeric ligand and nitrogenous polymeric metal complex are presented by adopting elemental analysis, Fourier transform infrared, atomic absorption, thermogravimetric analysis (TGA) and electron spin resonance (ESR) etc., and catalytic performance of the nitrogenous polymeric metal complex on acetal (ketone) reaction and alcohol oxidation is inspected. The results indicate that polymeric metal complex can be really formed by making functionalized polystyrene acting on transition metal salt in certain conditions, and various N-functionalized nitrogenous polystyrene ligands have selectivity to the adsorption of metal ions.
