(57) [Summary] [Object] To provide a method for producing tris (acetylacetonato) ruthenium (III), which can improve yield and purity. [Structure] Ruthenium (III) chloride was dissolved in a solvent, acetylacetone was added to this solution to react, potassium hydrogencarbonate was added to this reaction solution to cause reaction, and the mixture was extracted with benzene, and then the benzene solution was concentrated and collected by filtration. After that, by washing and drying, precipitation of ruthenium can be prevented and the amount of acetylacetone can be reduced. |
