AB  - Densities, viscosities, speeds of sound and refractive indices have beenmeasured for the ternary systemethyl oleate+ n-hexadecane+1-butanol, and for the corresponding binaries ethyl oleate+1-butanol and ethyl oleate+ n-hexadecane, in the temperature range fromT=(293.15 to 343.15) K and at atmospheric pressure. Experimental data were employed to calculate some derived thermodynamic parameters, i.e. excess molar volumes (V-E), viscosity deviations (Delta eta.) and deviations in refractive index (.nD). Additionally, molar excess Gibbs free energies of activation of viscous flow (Delta G*(E)) and deviations in isentropic compressibility (Delta kappa(s)) were calculated. A graphical representation of excess molar volumes and refractive indices show positive deviation from ideal behavior for both binary systems whereas deviation in viscosity shows negative nature for the ethyl oleate + n-hexadecane system and an inversion sign for ethyl oleate +1-butanol binary system. A negative deviation in isentropic compressibility was confirmed for the systems ethyl oleate +1-butanol while positive deviation was observed in ethyl oleate + n-hexadecane system. It can be concluded that dispersive forces predominate between the components in binary systems and the observed behavior seems to suggest that the properties obtained for the ternary mixture are dominated by the binary effects. The viscosities of the binary systems were modeled by UNIFAC-VISCO, ASOG-VISCO, Teja-Rice and McAllister models. The results showed that McAllister's multibodymodel is suitable to describe viscosities for binary systemswithmaximumpercentage deviations less than 0.5%.

AB  - Densities (rho), viscosities (eta), speed of sounds (u) and refractive indices (n(D)) at temperature range (293.15-343.15) K with 5 K interval, for three binary mixtures (1-propanol + n-hexadecane, 1-butanol + n-hexadecane and 1-propanol + ethyl oleate), were measured at atmospheric pressure. Based on the corresponding experimental data, excess molar volume (V-E), viscosity deviation (Delta eta) and deviation in refractive index (Delta n(D)) have been calculated. Beside these properties, molar excess Gibbs free energies of activation of viscous flow (Delta*G(E)) and deviation in isentropic compressibility (Delta k(s)) were calculated from measured density, viscosity and speed of sound data. The excess/deviation functions have been fitted by Redlich-Kister equation and discussed in terms of molecular interactions existing in the mixtures. Viscosity modeling was performed using four models: UNIFAC-VISCO, ASOG-VISCO, Teja-Rice and McAllister. Experimental viscosity data have been used to determine new binary UNIFAC-VISCO and ASOG-VISCO interaction parameters and the interaction parameters for correlation models by applying some optimization technique. For all systems, positive deviations were observed for the excess molar volumes in the whole concentration range. A negative deviation and an inversion sign for the excess dynamic viscosity were observed in the systems of 1-butanol + n-hexadecane and 1-propanol + n-hexadecane, respectively, while positive deviation was observed for 1-propanol + ethyl oleate mixture. The results of viscosity modeling showed that four-body McAllister models are suitable to describe viscosities for all systems and temperatures with maximum percentage deviations (PDmax) less than 0.5%.

AB  - Densities, speeds of sound, and refractive indices of methyl laurate, ethyl laurate, ethyl myristate, and ethyl oleate in the temperature range 288.15-343.15 K and viscosities from 288.15 to 373.15 K were measured at atmospheric pressure. The measured properties were in good agreement with several available literature data, finding an overall absolute average percentage deviation (AAD) of 0.04%, 0.07%, 3%, and 0.1% for density, speed of sound, viscosity, and refractive index, respectively. The densities of mentioned esters were also measured along 15 isotherms from 293.15 to 413.15 K and at pressures up to 60 MPa using an Anton Paar DMA HP densimeter. Based on the literature data selected for comparison, in the studied ranges of temperature and pressure, the AADs of high-pressure densities were 0.08% for methyl laurate, 0.06% for ethyl laurate, and 0.05% for ethyl myristate. The obtained density values were correlated through the modified Tammann-Tait equation with an AAD lower than 0.009% for all the studied esters. The adjusted parameters were used to calculate the isothermal compressibility, isobaric thermal expansivity, internal pressure, and difference in isobaric and isochoric heat capacities. It was found that methyl laurate has higher density, speed of sound, and refractive index than ethyl laurate of the same fatty acid, while viscosities for the ethyl are slightly higher than those of the methyl laurate. The values of the isothermal compressibility and the isobaric thermal expansivity for ethyl laurate are slightly higher than those for methyl.
