摘要

Rh nanoparticles were investigated as a catalyst for hydroformylation of olefins in thermoregulated ionic liquid/organic biphasic systems composed of an ionic liquid, namely [CH₃(OCH₂CH₂)₁₆N⁺Et₃][CH₃SO₃^{鈭?/sup>] (IL_PEG750), and an organic solvent. This enables not only a homogeneous reaction but also easy biphasic separation. Under the optimized reaction conditions, the conversion of 1-octene and yield of aldehyde were 99%and 91%, respectively. The catalyst was easily separated from the product by phase separation and used eight times without evident loss of activity.}
