Abstract
In a process for the hydroformylation of ethylenically unsaturated compounds, at least one complex or compound of a metal of transition group VIII with at least one bidentate phosphine ligand is used as hydroformylation catalyst and at least one of the reaction steps following the hydroformylation reaction is carried out essentially in the absence of carbon monoxide and hydrogen and in the presence of at least one monodentate phosphine ligand.
