Product Description
Acetylacetone is a derivative of acetone; chemical formula: CH3COCH2COCH3; It is colorless to pale yellow transparent liquid. It is usually the mixture is enol form and keto form which are the tautomers of each other; these two forms are in dynamic equilibrium; enol isomer forms hydrogen bonds inside the molecule; in the mixture, the keto form accounts for about 18% and enol type accounted for 82%. Cool the petroleum ether of their mixture to-78 °C so the enol will be precipitated as a solid and the two forms will be separated with each other. Upon the enol form being returned back to room temperature, the above equilibrium will be restored.
