| Physical and Chemical Properties | Copper acetylacetonate also known as 2.4-pentanedione copper, blue needle-like crystals or powder. Slightly soluble in water and ethanol, soluble in chloroform, benzene and carbon tetrachloride. Resistance to hydrolysis. Its trifluoro derivative, called copper trifluoroacetylacetonate [Cu(OCCH3CHCOCF3)2], is a solid with a melting point of 188-190 °c. Toxic, used as a reference for metal analysis and vapor deposition of metals. |

| production method | preparation method 10g(0.041mol) copper nitrate trihydrate (ii) is dissolved in 100mL of water and 15mL of concentrated ammonia water is added. 11mL of acetylacetone was added to the solution containing cupramine complex ion [Cu(NH3)4]2 + under stirring to obtain a blue precipitate. Filtration, washing with water, natural drying to obtain 10.6g of crude product with 98% yield. Recrystallization with methanol-chloroform or benzene-chloroform mixed solvent. |
