A process for the hydroformylation of olefins to produce oxygenated compounds comprises reacting together an olefin, carbon monoxide and hydrogen at elevated temperature and pressure in the presence of a rhodium-containing hydroformylation catalyst and an amount of cobalt or a cobalt compound not exceeding that corresponding to 100 ppm w/w of cobalt metal on the olefin. The reaction is carried out homogeneously and in the absence of a phosphorus-containing organic ligand. The addition of cobalt or a cobalt compound facilitates the reaction of less reactive olefin feedstocks or feedstocks which contain certain impurities. |
