Density, Refractive Index, Viscosity, and Speed of Sound in Binary Mixtures of Ethenylbenzene with Hexane, Heptane, Octane, Nonane, Decane, and Dodecane

Abstract

Experimental densities, refractive indices, and viscosities at 298.15, 303.15, and 308.15 K and speeds of sound values at 298.15 K are presented for the binary mixtures of ethenylbenzene with hexane, heptane, octane, nonane, decane, and dodecane over the entire compositions. From these data, excess molar volumes, deviations in refractive index, speed of sound, and viscosity have been computed. These parameters have been fitted to the Redlich−Kister equation using a multiparametric nonlinear regression analysis. Estimated coefficients and standard error values for the mixing quantities are presented for each of the binary mixtures. Experimental and computed results are discussed in terms of molecular interactions.
