In an improved process for hydroformylation of olefinically unsaturated compounds using a catalyst based on cobalt and/or rhodium employed in a two-phase medium, a catalyst based on cobalt and/or rhodium is used dissolved in a non-aqueous ionic solvent which is liquid at a temperature of less than 90&deg; C., in which the aldehydes formed are slightly soluble or insoluble. More particularly, the catalyst comprises at least one complex of cobalt and/or rhodium co-ordinated with at least one nitrogen-containing ligand and the non-aqueous ionic solvent comprises at least one quaternary ammonium and/or phosphonium cation and at least one inorganic anion. At the end of the reaction, the organic phase is generally separated and the ionic non-aqueous solvent phase containing the catalyst can be re-used.

Process for hydroformylation using a catalyst based on cobalt and/or rhodium employed in a two-phase medium

The invention concerns a process for alkylating isoparaffins by olefins using a novel catalyst, the olefin preferably being a low reactivity olefin. The catalyst is a composition resulting from a mixture of at least aluminum halide, at least one quaternary ammonium halide and/or at least one amine hydrohalide and at least one group IVB metal compound, preferably a group IVB metal halide.
