Abstract

Through the study of the critical solution temperature of ionic liquids [CH₃(OCH₂CH₂)_n N⁺Et₃] [CH₃SO₃^-] (IL_PEG, n = 12, 16, 22), IL_PEG-stabilized Rh nanoparticle catalysts have been found to function as thermoregulated phase-separable catalysts and have been shown to be efficient and recyclable for the selective hydrogenation of 1, 5-cyclooctadiene (1, 5-COD) to cyclooctene (COE). Under optimized conditions, the conversion of 1, 5-COD and selectivity for COE were 99% and 90%, respectively. The Rh catalyst could be recovered by simple phase separation and reused for ten times without loss of activity or selectivity.
