摘要：

Two novel ether-based perrhenate ionic liquids 1-(2-methoxyethyl)-3-ethylimidazolium perrhenate ([C22O1Im][ReO4]) and1-(2-ethoxyethyl)-3-ethylimidazolium perrhenate ([C22O2Im][ReO4]) were synthesized and characterized by nuclear magnetic resonance spectroscopy (1H NMR,13C NMR), Raman spectroscopy (Raman), electrospray ionization mass spectrometry (ESI-MS), differential scanning calorimetry (DSC). As a sort of organic synthesis intermediates which is chemically active and easily converted into other substances, epoxy compounds occupy an extremely important position in various industries of national production. The epoxidation of olefins is an important way to synthesize epoxy compounds. Therefore, two novel ether-based perrhenate ionic liquids were used as catalyst and solvent in the reaction system of cyclooctene epoxidation to epoxycyclooctane, respectively. The effects of reaction temperature, time, oxidant amount, catalyst amount and its recycle were investigated systematically. The results showed that the yield was more than 90%, the reaction selectivity was more than 99%, the catalyst was cycled 5 times, and the yield did not decrease significantly. © All Right Reserved.
