Abstract

A heteropolyanion-based cross-linked ionic copolymer was prepared by the anion-exchange of a newly task-specific designed amino-containing ionic copolymer with a Keggin heteropolyacid, and characterized by FT-IR, SEM, TG, XRD, UV-vis, ESR, ¹H NMR, and elemental analysis. Its catalytic activity was evaluated in the epoxidation of alkenes with aqueous H ₂O₂. The resultant heteropolyanion-based ionic copolymer is revealed to be a highly efficient heterogeneous catalyst for epoxidation of alkenes with H₂O₂, adding the advantages of convenient recovery and steady reuse.
