Excess Molar Volumes and Viscosities of Binary Mixtures of Dimethyl Carbonate with Chlorobenzene, Hexane, and Heptane from (293.15 to 353.15) K and at Atmospheric Pressure

Abstract

Densities and viscosities for the dimethyl carbonate (DMC) + (hexane, heptane, chlorobenzene) binary systems have been experimentally determined from (293.15 to 353.15) K and at normal atmospheric pressure over the entire mole fraction range. Other mixing properties of interest such as the excess molar volumes and the viscosity deviations have also been obtained for each of the systems. The obtained properties have been compared with those reported by other authors in the literature and have been analyzed in terms of the molecular interactions present in this kind of mixture. The excess molar volumes for these three binary systems were positive over the whole composition range at all temperatures. On the contrary, the deviations of viscosity for DMC + hexane and DMC + heptane are negative, and those for DMC + chlorobenzene are very small.
