Thermodynamic Excess Properties of Binary Mixtures of Acetyl acetone and Ethyl Acetate

The density (ρ), viscosity (η), surface tension (σ), and refractive index (R) of binary mixtures acetylacetone (acac) with ethyl acetate (Etac) were determined at atmospheric pressure over the entire composition range mixtures. values pure liquids have been used to calculate excess volume (VE), deviation in (Δη), tension. computed results fitted Redlich–Kister polynomial equation. molar (VE) for system investigated exhibits a positive 298.15 K, 303.15 K becomes too negative as mole fraction Xacac increases. (Δη) (Δσ) show from ideality magnitude suggests presence strong intermolecular interactions between unlike molecules
