- W2076761680 abstract "A comparative study of the catalyzed decomposition of hydrogen peroxide using the following copper(II) complex salts, Cu(bipy)(S-threo)Cl · 3H2O, Cu(phen)(S-threo)Cl · 2H2O, Cu(bipy)(S-prol)Cl · 2H2O and Cu(phen)(S-prol)Cl · 2H2O has been made. Kinetic parameters were experimentally determined by the polarographic method at 25°C, pH 7.7 and constant ionic strength (μ = 0.1 M NaNO3). The catalytic behavior of the chelate with 2,2′-bipyridine and S-prolinate was also studied at pH 6.5 and 8.5. The reactivity follows the sequence: [Cu(bipy)S-prol] > [Cu(phen)S-prol] > [Cu(bipy)S-threo] > [Cu(phen)S-threo]. Activation energies are very similar to each other. The pH-dependent exchange of the amino acid ligand with hydrogen peroxide seems to be a critical factor in the reaction pathway. Several reaction mechanisms are proposed." @default.
