A process is described for the hydroformylation of olefinically unsaturated compounds whose hydroformylation products are insoluble or only sparingly soluble in water. The reaction is carried out in a homogeneous phase in a polar organic solvent as reaction medium. The catalyst system which comprises a rhodium carbonyl compound and the salt of a sulfonated or carboxylated organic phosphine is soluble both in the polar organic solvent and in water. For the work-up, the polar organic solvent is distilled off from the homogeneous reaction mixture and the catalyst system is separated from the distillation residue using water.
