Abstract: The synthesis of α- and β-Cs<H3[SiW9O37Cr3(H2O)3] β xH2Oand their catalysis for epoxi-dation of olefin are reported.The heteropolyacid salts have an ability to catalyze the epoxidation of olefin by PhIO, and the catalytic activity of them is probably related to the fact that the substituted Cr ( Ⅲ ) can be oxidized to a higher oxidation state and the compound with a higher oxidation state has an oxidation property.
Key words: Trichromononatungstosilicate, Trisubstituted keggin heteropolyanion, Epoxidation of olefin
