    Abstract: A hydroformylation process for unsaturated compounds such as monoolefins and diolefins is carried out in an ionic medium in which the catalytic species is dissolved, but in which the reaction products (aldehydes) formed are only slightly soluble or are insoluble. The ionic medium is liquid at a temperature below 90.degree. C. and comprises at least one quaternary ammonium and/or phosphonium cation and at least one anion which is preferably selected from the group formed by tetrafluoroborate when the cation is ammonium, hexafluorophosphate, hexafluoroantimonate, hexafluoroarsenate, perfluoroalkylsulphonates, fluorosulphonate, bis-perfluoroalkylsulphonyl amides or dichlorocuprate, tetrachlorocuprate, tetrachloroaluminate, or trichlorozincate. At the end of the reaction, the organic phase is separated out and the polar phase containing the catalyst is used again.
