Process for the hydroformylation of olefinically unsaturated compounds in a non-aqueous ionic solvent

In a process for hydroformylation of olefinically unsaturated compounds using a catalyst based on cobalt and/or rhodium co-ordinated by at least one ligand selected from the group formed by nitrogen-containing or phosphorus-containing ligands used in a non-aqueous ionic solvent, which catalyst is liquid at a temperature of less than 90&deg; C., in which the aldehydes formed are not or are only slightly soluble and which comprises at least one quaternary ammonium and/or phosphonium cation Q and at least one anion A , the improvement of the invention consists in that in the cobalt and/or rhodium complex, the ligand also carries an ionic function (Q&prime;) (A&prime;) where Q and Q&prime; and/or A and A&prime; are chemically identical.

Hydroformylation process employing a catalyst based on cobalt and/or rhodium in a non-aqueous ionic solvent

Process for the preparation of an ionic compound, Q,A,liquid at less than 150&deg; C., wherein a trialkyloxonium of the anion is reacted with an amine in a hydrocarbon solvent. The aforesaid ionic compound can be used as a solvent in numerous catalytic reactions.
