Amino-containing cross-linked ionic copolymer-anchored HPA catalysts were prepared by the anion-exchange of polydivinylbenzene/amino-functionalized ionic liquids copolymers with Keggin heteropoly acid (HPA), and were characterized by 1H NMR, FT-IR, TG, XRD, SEM, TEM, BET surface area, and elemental analysis. Their catalytic performance for oxidation of benzyl alcohol with H2O2 was studied under solvent-free conditions. The results demonstrated that the catalysts were very active and selective, and could be reused after simple separation.
A new amino-containing cross-linked ionic copolymer-anchored heteropoly acid (HPA) catalyst by the anion-exchange of amino-containing crossed-linked ionic copolymer with Keggin HPA. The catalyst was revealed to be a highly active and selective solid catalyst for solvent free oxidation of benzyl alcohol with H2O2, and could be reused by simple filtration.Figure optionsDownload as PowerPoint slideHighlights
