- 摘要： Heteropoly anion [PMo4O24](3-) (PMo) was immobilized on the quaternary-ammonium poly(phthalazinone ether sulfone ketone) (QAPPESK) support by taking advantage of the overall negative charge of anion. The supported catalyst QAPPESK-PMo was fully characterized by FT-IR and XRD. The results of analyses indicated that the PMos were finely dispersed on the polymer support via chemical interactions. This supported catalyst was employed to catalyze oxidation of olefins with hydrogen peroxide, and satisfying results were obtained under mild heterogeneous conditions. The effects of various reaction factors, such as solvent, the amount of H2O2 and catalyst used, were studied. Furthermore, the leaching and recycling tests revealed that the supported catalyst was highly efficient and robust. (c) 2008 Elsevier B.V. All rights reserved.
