| Abstract: | The solubility of acetoacetylferrocene and 1,1′-bis(acetoacetyl)ferrocene in water and aqueous ethanol at various temperatures is studied over a wide solvent composition range. The solubilities of both compounds increase as the temperature or ethanol concentration is raised, particularly in the case of acetoacetylferrocene. The dissolution of both β-diketones is accompanied by positive changes in enthalpy and entropy. |
