| Abstract: | The four heteropoly isomers K3H2 α-,βi-SiW11 Fe (H2O) O39]·χH2O (βi =β1,β2,β3) were prepared and Characterized by elementary analysis, IR and UV Spectroscopy. Its electrochemical behavior in aqueous solution has been discussed. The order of Polarographic half-wave potential E1/2 of heteropoly anions is as follows: β2>β1>β3>α. Its reduction process involves an one-electron reduction of Fe (Ⅲ) and a pair of two-electron reduction of W (Ⅵ). Epolidation of maleic acid with H2O2 Catalyzed by heteropoly positional isomers was studied. β3 isomers are the most active |
