    Abstract: PROBLEM TO BE SOLVED: To provide a method for hydroformylating an olefin having at least 6 carbon atoms that achieves as high conversion as possible for a given reactor volume. SOLUTION: At least one kind of olefin is introduced along with synthesis gas at the lower end of the first reaction chamber and then the reaction mixture reacted in part is introduced to the lower end of the second reaction chamber out of the upper end of the first reaction chamber and then the hydroformylated olefin is taken out at the upper end of the second reaction chamber, using a vertically long cylindrical reactor of which the internal space is divided by a partition into at least two reaction chambers essentially extended to the longitudinal direction of the reactor.

Date Sep. 21, 1995An industrial preparation of aldehydes and/or alcohols from olefins of more than 3 carbon atoms by a catalytic hydroformylation of the olefin reactant at a pressure of from 50 to 1000 bar and a temperature of from 50 to 180 DEG C. in the presence of an uncomplexed rhodium catalyst homogeneously dissolved in the reaction medium. The catalytic activity of the rhodium is maintained, first by extracting it from the initially discharged reaction mixture by means of an aqueous solution of a nitrogen-containing complexing agent such as sulfonated or carboxylated pyridines, quinolines or the like. In a recycle of the complexed rhodium to be reused in the hydroformylation reaction, the aqueous rhodium-containing extract is fed to a precarbonylation stage where it subjected to a required precarbonylation in the presence of an essentially water-insoluble organic liquid and in the presence of carbon monoxide, synthesis gas or another gas mixture containing carbon monoxide at from 50 to 1000 bar and from 50 to 180 DEG C. The mixture discharged from this precarbonylation stage is then separated into an organic phase containing the main part of the rhodium and an aqueous phase containing the complexing agent. The resulting rhodium-containing organic phase with the regenerated catalyst is then fed into the hydroformylation stage to complete its recycle.
