Abstract (en)

[origin: DE19730783A1] The invention relates to a method for producing oxo products by hydroformylation of substrates with C=C double bonds, using unmodified rhodium catalysts in a reaction mixture consisting essentially of the substrates, the catalyst and carbon dioxide in a supercritical state (scCO2). The invention especially relates to methods of this kind for producing products containing substantial parts of branched i-oxo products. The invention further relates to methods of this kind for the hydroformylation of substrates not corresponding to the general formula C2H2n. The invention also relates to said methods in which the product and catalyst are separated using the special solubilizing properties of scCO2.
