DENSITY, REFRACTIVE-INDEX, VISCOSITY, AND SPEED OF SOUND IN BINARY-MIXTURES OF ETHENYLBENZENE WITH HEXANE, HEPTANE, OCTANE, NONANE, DECANE,AND DODECANE

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 prese nted for the binary mixtures of ethenylbenzene with hexane, heptane, o ctane, nonane, decane, and dodecane over the entire compositions. From these data, excess molar volumes, deviations in refractive index, spe ed of sound, and viscosity have been computed. These parameters have b een fitted to the Redlich-Kister equation using a multiparametric nonl inear regression analysis. Estimated coefficients and standard error v alues for the mixing quantities are presented for each of the binary m ixtures. Experimental and computed results are discussed in terms of m olecular interactions.
