<p>The invention relates to a process for preparing an aldehyde starting from an unsaturated compound by means of hydroformylation in the presence of hydrogen, carbon monoxide, platinum and a bidentate ligand, the hydroformylation being effected in an aqueous medium and the bidentate ligand being a water-soluble compound. The invention also relates to a process for preparing an aldehyde, in which the following steps are carried out: a) preparation of the aldehyde in a reaction zone using a process as described above, b) isolation of the aldehyde from the aqueous mixture leaving the reaction zone by extraction, c) recycle of the aqueous mixture of step b) to the reaction zone.</p> |
