) were synthesized and characterized by nuclear magnetic resonance spectroscopy (

H NMR

C 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 re

cycle 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.
