Peroxotungstate Immobilized on Ionic Liquid-Modified Silica as a Heterogeneous Epoxidation Catalyst with Hydrogen Peroxide

摘要

W2/1—SiO_2 was capable of heterogeneously epoxidizing a broad range of olefins with high selectivity. The activity and selectivity were comparable to those of the homogeneous analogue, showing that the homogeneous catalysis could be heterogenized.
