Densities, Refractive Indices, and Derived Excess Properties of the System Methyl Acetate + Methanol + 2-Butanol at 298.15 K

摘要: This work reports the experimental results of densities and refractive indices ternary system methyl acetate + methanol 2-butanol corresponding binary systems at 298.15 K atmospheric pressure. A vibrating tube digital densimeter a refractometer synthetic sapphire prism (sodium D wavelengh) were used, whole mole fraction range being covered. Excess molar volumes changes index on mixing determined from data, different estimation equations that are dependent contributions analyzed. Variable-degree polynomials have been fitted to results. Values evaluated compared by methods. partial those infinite dilution condition also calculated.
