  • Hydroformylation process
    Patent number: 4277627
    Abstract: A process for the hydroformylation of alpha-olefins employing a rhodium catalyst complexed with carbon monoxide and a triarylphosphine wherein the intrinsic deactivation of the rhodium catalyst which occurs under hydroformylation conditions is inhibited or substantially prevented by determining and correlating the reaction conditions of temperature, carbon monoxide partial pressure and the free triarylphosphine: catalytically-active rhodium metal mole ratio. These conditions can be determined from a mathematical relationship between the combination of these variables and the stability of the rhodium complex catalyst.
