Abstract: The densities and kinematic viscosities of the binary systems methyl butanoate+n-heptane, methyl butanoate+n-octane and n-heptane+n-octane have been determined at 283.15, 293.15, 303.15 and 313.15 K and atmospheric pressure for the whole composition range. The same properties were determined, as well, for the ternary system methyl butanoate+n-heptane+n-octane at 283.15 and 313.15 K. The binary excess volumes were correlated to both composition and temperature in order to obtain other properties such as the isobaric thermal expansion coefficients, the temperature coefficients of the molar excess volume and the pressure coefficients of the molar excess enthalpy. These properties and the excess volumes of the binary and ternary mixtures were compared to those forecasted by the group-contribution model proposed by Nitta et al. using parameter sets previously reported in the literature. The kinematic and dynamic viscosities of both types of systems were used to evaluate the performance of several empirical and semi-empirical correlation models available in the literature. Also, viscosity values were checked against those predicted by the group-contribution models UNIFAC-VISCO and UNIVAC. Finally, both the excess volumes and viscosity deviations of the ternary systems were compared to results from several models for prediction of ternary properties based on experimental results from binary systems.
