The experimental densities and viscosities of Methyl Ethyl Ketone with Ethyl Benzene at temperatures of 303.15, 308.15 and 313.15 K were determined using a Ostwold-Sprengal- type pycnometer and Oswald 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.
