Abstract

Experimental densities, viscosities, and refractive indices at 298.15, 303.15, and 308.15 K as well as the speed of sound at 298.15 K are presented over the entire mole fraction range for the binary mixtures of ethenylbenzene (styrene) with methanol, ethanol, butan-1-ol, pentan-1-ol, and hexan-1-ol. The calculated excess molar volume data have been compared with the Flory as well as the Prigogine−Flory−Patterson (PFP) theories. The deviations in logarithmic viscosity have been compared with the computed values of the Bloomfield and Dewan equation. Refractive index data have been used to calculate the deviations in the Lorentz−Lorenz molar refractivity. From the speed of sound data, the isentropic compressibility and isothermal compressibility have been calculated and compared respectively with the values computed by Benson−Kiyohara and the values from the Flory equation. All the computed quantities have been fitted to the Redlich and Kister equation to estimate the regression coefficients and standard err...
