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 ov
er 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 a
s well as the Prigogine-Flory-Patterson (PFP) theories. The deviations in l
ogarithmic viscosity have been compared with the computed values of the Blo
omfield and Dewan equation. Refractive index data have been used to calcula
te the deviations in the Lorentz-Lorenz molar refractivity. From the speed
of sound data, the isentropic compressibility and isothermal compressibilit
y have been calculated and compared respectively with the values computed b
y 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 errors. The sign and magnitude of
the mixing quantities have been discussed in terms of the intermolecular in
teractions between ethenylbenzene and n-alkanols.
