  • Patent number: 6452055
    Abstract: This invention relates to a process for the catalytic hydroformylation of olefins by reaction of an olefin with hydrogen and carbon monoxide in a liquid, aqueous-organic reaction medium in the presence of a water-soluble hydroformylation catalyst, characterized in that for a substantial period of the hydroformylation reaction, the aqueous-organic medium is present in the form of a microemulsion, which is made up of an oil phase containing the olefin or the olefin and its hydroformylation products, an aqueous phase containing the water-soluble complex catalyst, and a nonionic surfactant.
