Densities and Viscosities of Binary Mixtures of Ethylbenzene + N-Methyl-2-pyrrolidone, Ethylbenzene + Sulfolane, and Styrene + Octane from (303.15 to 353.15) K and Atmospheric Pressure

The experimental densities and viscosities of ethylbenzene + sulfolane and ethylbenzene + N-methyl-2-pyrrolidone at temperatures of (303.15 to 353.15) K and of styrene + octane at temperatures of (293.15 to 363.15) K were determined using a vibrating-tube density meter and Ubbelohde viscometer. From these data, excess molar volumes and viscosity deviations have been calculated. The computed quantities have been fitted to the Redlich−Kister equation to derive the coefficients and estimate the standard error values. The results are discussed in terms of the intermolecular interactions.
