An improved catalyst composition for the hydroformylation of olefinically unsaturated compounds using catalytically active organometallic complexes wherein said complexes are dissolved in a ligand-forming compound and impregnated into a porous solid carrier material which is essentially free of alkali metal ions and acid or basic groups which would otherwise be reactive with the organo-metallic commplex.

Heterogeneous catalyst on the basis of an organometallic complex

Olefinically unsaturated compounds are subjected to hydroformylation to produce the corresponding aldehyde having an additional carbon atom by reacting the compound with hydrogen and carbon monoxide under appropriate conditions of temperature and pressure in the presence of a catalytically active metallo-organic complex in the pores of a solid porous carrier in the form of a solution in a ligand-forming electron-donating phosphorous compound, such as triethyl phosphine, that has a vapor pressure of less than 15 mbar under reaction conditions. The central atom of the metallo-organic complex is preferably rhodium, cobalt, ruthenium or irridium.
