Abstract

The invention relates to a hydroformylation process in which at least one olefin having from 2 to 6 carbon atoms is reacted continuously with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst in a reaction zone in which a liquid phase is present and a stream S) is taken from the liquid phase, heat is removed from this stream and the stream is subsequently returned to the reaction zone without removal of a material component.
