Patent Searching and Data

Document Type and Number:
Japanese Patent JP2001510176
Kind Code:
The present invention relates to processes for the preparation of oxo products by the hydroformylation of substrates having C=C double bonds using unmodified rhodium catalysts in a reaction mixture essentially consisting of the substrates, the catalyst and carbon dioxide in a supercritical state (scCO2). In particular, the invention relates to such processes for the preparation of products which contain substantial proportions of branched i-oxo products. Further, the invention relates to such processes for the hydroformylation of substrates which do not correspond to the general formula CnH2n. The invention further relates to such processes in which the separation of product and catalyst is effected using the special solvent properties of scCO2.
