The density and viscosity of binary liquid mixtures of propylene carbonate with polar and nonpolar solvents (acetone, chloroform, 1,4-dioxane benzene, toluene, and o-xylene) have been measured at 303.15 K. From density and viscosity data, the values of excess molar volume (V-E) and deviations in viscosity (deltaeta) have been determined. The excess molar volume and deviations in viscosity are negative over the entire range of composition. The density and viscosity data have been theoretically analyzed for the validity of different viscosity models.
