Abstract
In a primary process for hydroformylating olefins in the presence of a rhodium-containing catalyst solution to produce aldehydes and a gaseous effluent comprising unreacted olefin is vented, the improvement which comprises employing the effluent as a reactant feed for a coupled secondary hydroformylation process conducted jointly therewith in which the catalyst solution is cycled back and forth between the primary and secondary hydroformylation processes.
