Hydroformylation of higher olefins such as 1-hexene, 1-octene, 1-decene and 1-dodecene has been studiedin an aqueous biphasic medium using water-soluble Rh-sulfoxantphos complex catalyst. The effect oftemperature, presence of various co-solvents and concentration of co-solvent on the reaction rate andchemo and regioselectivity was investigated. N-Methyl pyrrolidone (NMP) was found to be the bestco-solvent, which enhances the rate dramatically (4-96 fold) as compared to the reactions inaqueous-organic biphasic medium for hydroformylation of higher olefins. Catalyst recycle study wasperformed to check the leaching of metal in organic phase.
