Abstract: 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] (ILPEG750), 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.

Key words: hydroformylation, rhodium, nanoparticle, olefin, thermoregulated ionic liquid/organic biphasic system
