| description | The oxidation of ethylbenzene using dioxygen was carried out applying a new catalytic system—heterogeneous <i>N</i>-hydroxyphthalimide (PS-NHPI) coated with an ionic liquid containing CoCl<sub>2</sub>. The catalytic system represents a combination of solid catalyst with ionic liquid layer (SCILL) and supported ionic liquid phase (SILP) techniques, wherein the resulting system utilizes CoCl<sub>2</sub> dissolved in the 1-ethyl-3-methylimidazolium octyl sulphate ([emim)][OcOSO<sub>3</sub>]) ionic liquid phase that is layered onto the solid catalyst support. PS-NHPI was obtained by immobilizing <i>N</i>-hydroxyphthalimide on chloromethyl polystyrene resins by ester bonds. It was observed that novel SCILL/SILP systems significantly improved the selectivity toward acetophenone. We also demonstrate that these systems can be separated from the reaction mixture and recycled without appreciably reducing its activity and selectivity. |
