摘要： Recovery of rhodium from rhodium complexes comprises: (i) extraction of the organic phase with an aqueous solution of a phosphate or phosphonate; and (ii) treating the organic phase with an oxidizing agent and with an aqueous solution of an arylphosphine at increased temperature and pressure to recover the rhodium-containing aqueous solution from the organic phase. A process for the recovery of rhodium from rhodium complexes, optionally cobalt complexes and optionally complex ligand-containing organic solutions comprises: (i) extraction of the organic phase with an aqueous solution of a phosphate of formula (1) or phosphonate of formula (2); (ii) washing the organic phase with water at pH 0-8; (iii) treating the organic phase with an oxidizing agent at 0-100 [deg]C; (iv) treating the organic phase with an aqueous solution of a water-soluble arylphosphine at increased temperature and pressure; and (v) phase separation of the rhodium containing aqueous solution (I) from the organic phase. (O)P(OR1>)(OR2>)(OR3>) (1) R4>P(O)(OR5>)(OR6>) (2) R1>-R6>H, 1-10C alkyl or 6-10 C aryl, optionally substituted with 1-4C alkyl. Independent claims are also included for: (i) A catalyst for hydroformylation of aldehydes, comprising the recovered aqueous rhodium-containing solution (I) (ii) A process for the treatment of the recovered rhodium-containing aqueous solution (I) at 50-200 [deg]C and 0.1-2.0 MPa with an oxidizing agent followed by extraction using an organic (di)phosphine-containing organic solvent. (iii) The recovered rhodium-containing organic solution (II).

摘要： The invention relates to a hydroformylation method, whereby the homogeneous liquid reactor discharge is first supplied to a gas/liquid separator and then run through an extraction column with a counter-current of synthesis gas and finally fed to an evaporator. The invention is characterised in that the homogeneous liquid mass flow is supplied to the upper section of the extraction column at a temperature above 90° C.
