The invention provides a catalyst system composed of: Additionally provided is the use of the catalyst systems of the invention in the oligomerization of unsaturated hydrocarbon mixtures.

Process for oligomerizing olefins

The present invention provides a composition comprising: a) an inert porous support material, b) an ionic liquid, c) a metal selected from group 9 of the Periodic Table of the Elements, d) a phosphorus-containing organic ligand, e) at least one organic amine. The present invention further provides a process for hydroformylating olefin-containing hydrocarbon mixtures to aldehydes with addition of the inventive composition as a catalytically active composition, wherein: a) the water content of the olefin-containing hydrocarbon mixture is adjusted to not more than 20 ppm, b) the content of polyunsaturated compounds in the olefin-containing hydrocarbon mixture is adjusted to not more than 3000 ppm, c) a molar ratio of organic amines according to claims-to phosphorus-containing organic ligands according to claims-of at least 4:1 is established, d) a molar ratio of phosphorus-containing organic ligands according to claims-to rhodium of at least 10:1 is established.

Use of supported ionic liquid phase (SILP) catalyst systems in the hydroformylation of olefin-containing mixtures to aldehyde mixtures with a high content of aldehydes unbranched in the 2 position
