摘要： A process of controlling heavies in a recycle catalyst stream, particularly, for use in a continuous hydroformylation process of converting an olefin with synthesis gas in the presence of a hydroformylation catalyst to form an aldehyde product stream with subsequent separation of the catalyst for recycle to the hydroformylation step. Heavies are controlled, and preferably reduced, by means of feeding a recycle gas stream, taken as a portion of an over-head stream from a condenser, back to a vaporizer wherein the aldehyde product stream is separated.
