    摘要: PURPOSE: A solution of a complex of noble metal of group VIII containing a tertiary organophosphorus compound as a ligand is oxidized in a polar organic solvent in the presence of water and a base to produce the titled compound used as a hydrogeneration catalyst with industrial advantage.
    CONSTITUTION: An organic compound-containing solution of a complex of noble metal of group VIII containng a tertiary organophosphorus compound such as triphenyl phosphine as a ligand, e.g., a waste catalyst solution after hydroformylation of propylene with a rhodium-triphenylphosphine complex catalyst is brought in to contact with an oxidizing agent in the presence of free tertiary organophosphorus compound, a polar organic solvent such as ethanol, water and a basic substance such as sodium hydroxide to crystallize out the solid complex of noble metal of group VIII. Then, the crystals are filtered as the objective compound.
