ABSTRACT:
The disclosure describes a method for separating a ruthenium complex, which comprises removing an objective hydrogenation reaction product from a hydrogenation reaction solution of an organic carbonyl compound in the presence of a ruthenium complex having a tertiary organic phosphorus compound as ligand to obtain a catalyst solution, contacting said catalyst solution with a polar solvent, and carrying out a phase-separation into a liquid phase substantially composed of the polar solvent and an another liquid phase substantially containing the ruthenium complex.
