Basic ionic liquid supported on mesoporous SBA-15: An efficient heterogeneous catalyst for epoxidation of olefins with H2O2 as oxidant

Basic ionic liquid functionalized mesoporous silica SBA-15 was prepared and characterized by XRD, N2 adsorption–desorption, FT-IR and TEM. The catalyst demonstrated to be an efficient heterogeneous catalyst for olefin epoxidation using H2O2 as oxidant. The catalyst could be recycled at least five times without appreciable loss of catalytic activity.

Graphical abstractBasic ionic liquid functionalized mesoporous SBA-15 acted as an efficient base catalyst for the epoxidation of various olefins with hydrogen peroxide as oxidant in the presence of benzonitrile. The catalyst could be easily recycled without appreciated loss of catalytic activity for at least five times.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Basic ionic liquid functionalized mesoporous SBA-15 were prepared. ► Catalysts for epoxidation of olefins with H2O2 as oxidant. ► Good epoxide yields were achieved. ► Five times recycles without significant degradation in activity.
