ABSTRACT

Surface tension at T ) 298.15 K and atmospheric pressure has been measured for the ternary mixture dimethyl carbonate + p-xylene + n-octane. In addition, density and speed of sound at T ) (288.15 to 308.15) K have also been measured for the same mixture. Excess molar volumes, excess isentropic compressibilities, and surface tension deviations were computed from experimental data and correlated with the Cibulka equation. The excess molar volumes were compared with predictions from the Nitta et al. model.
