Abstract
The present invention relates to hydroformylation processes for producing aldehydes comprising: contacting in a reaction zone, reactants comprising an olefin, hydrogen and CO in the presence of a rhodium-organophosphite based catalyst, optionally with free organophosphite ligand, in the presence of a soluble Group VII metal complex additive, wherein the Group VII complex additive is present at greater than 2:1 molar ratio compared to rhodium.
Claims8
