Zusammenfassung:	PURPOSE:To obtain the titled compound in high yield and selectivity, by forming a ruthenium compound having high atomic valence from a ruthenium compound and an oxidizing agent such as sodium hypochlorite added continuously to the ruthenium compound and oxidizing 1,3-dichloropropan-2-ol in a reaction system having adjusted pH and containing the produced ruthenium compound. CONSTITUTION:A ruthenium compound having high atomic valence can be produced by adding an oxidizing agent (preferably sodium hypochlorite) continuously to at least one kind of ruthenium compound selected from ruthenium metal, its oxide, various ruthenium salts and their complexes. The reaction system is converted to a mixed solution consisting of a water-phase and an organic solvent phase, the pH of the water-phase is adjusted to
