Static permittivity, density, viscosity and refractive index of binary mixtures of anisole with 1-butanol and 1-heptanol at different temperatures

Abstract

Static permittivity, density, viscosity, and refractive index of anisole (AN), 1-butanol (1-BuOH), 1-heptanol (1-HeOH) and binary mixtures of AN with 1-BuOH and 1-HeOH at nine different concentrations, were measured at 303, 313 and 323K temperatures. Measured properties of pure AN, 1-BuOH and 1-HeOH were compared with literature values and they were found to be in good agreement. The investigation of binary mixtures showed a systematic change in static permittivity, density, and viscosity with change in concentration of anisole in the mixture. Measured properties of liquid samples were used to calculate Kirkwood correlation factor and excess parameters such as excess static permittivity, excess molar volume and excess viscosity. Determined parameters have been interpreted in terms of molecular interaction among the molecular species of the binary mixtures.
