Abstract
The invention relates to a method for reprocessing a liquid product of a hydroformylation reaction, wherein the liquid phase produced in a release stage is supplied to a separating device from which a liquid flow containing rhodium is guided away via a filter, where solids thereby separated are taken out of the process and the filtrate obtained is guided back into the hydroformylation reaction.
