Densities and viscosities of four ternary mixtures made from heptane, octane, nonane, and hexyl benzene were measured. The temperature ranged from 293.15 K to 313.15 K. The experimental viscosities of the four pure hydrocarbons and their ternary mixtures vs temperature were fitted to the Andrade equation with an average absolute deviation of 0.13 %. On the basis of these data, the excess molar volumes and viscosity deviations were calculated. The prediction results based on the Przezdiecki-Sridhar method and the Sastri-Rao method for low-temperature liquid viscosity estimation, the Dymond-Assael hard sphere model, and an equation of state based viscosity model proposed by Fan and Wang were compared with the experimental data.
