Abstract: | Densities and viscosities were measured for binary mixtures of isoamyl alcohol with 2-methoxyethanol, 2-ethoxyethanol, and
2-butoxyethanol over the entire range of composition at 303.15 K, 313.15 K, and 323.15K and ultrasonic speeds and refractive
indices at 303.15 K under atmospheric pressure. From the experimental values of density, viscosity, ultrasonic speed, and
refractive index, the values of excess molar volume (V
E), viscosity deviations (Δη), deviations in isentropic compressibility (ΔK
S
), and excess molar refraction (ΔR) have been calculated. The excess or deviation properties were found to be either negative or positive, depending on the
molecular interactions and the nature of liquid mixtures. |
