The excess molar volumes, V E , and viscosity deviations, ∆η, were calculated from the measured density and viscosity values over the whole miscibility composition ranges for the ternary systems water + butyl acetate + methanol and water + ethyl propionate + methanol and their constituent binaries, at 303.15 K and atmospheric pressure. A Redlich-Kister type equation was used to correlate binary V E and ∆η data, as well as the ternary data. This equation was used to calculate the above referred properties along the binodal curve.

Viscosities of the ternary mixture (2-butanol + hexane + 1-chlorobutane) at 298.15 K and 313.15 K have been measured at atmospheric pressure. Viscosity deviations for the ternary system were fitted to Cibulka's equation. To correlate experimental data of the ternary system, extended Nissan-Grunberg and McAllister equations have been used and their parameters have been calculated. The "viscosity-thermodynamic" model (UNIMOD) has been applied first to correlate experimental data for the binary mixtures and then to predict the viscosity for the ternary system. The group-contribution thermodynamic viscosity model (GC-UNIMOD) and the group contribution method proposed by Wu have been applied to predict the viscosity for the binary and ternary systems.

Experimental densities and excess molar volumes V E of one ternary and three binary systems containing 1-butanol, cyclohexylamine and n-heptane at temperatures from 283.15 to 323.15 K are reported. Density measurements were performed by an Anton Paar DMA 5000 vibrating tube densimeter. The obtained V E of binary systems were fitted to the Redlich-Kister equation, and to the Nagata-Tamura equation for the ternary system. For the correlation of V E data of binary systems van der Waals (vdW1) and Twu-Coon-Bluck-Tilton (TCBT) mixing rules coupled with the Peng-Robinson-Stryjek-Vera (PRSV) equation of state were applied. The same models were applied for the prediction and correlation of V E data of the ternary system. In addition, several empirical relationships were applied for the prediction of V E data of the ternary system from the corresponding binary data. The obtained results have been analysed in terms of specific molecular interactions present in the investigated mixtures taking into considerations the effect of temperature increasing on present interactions.

This article reports experimental values of densities of the ternary mixtures chlorobenzeneþn-hexaneþ(n-heptane or n-octane) at 298.15K and atmospheric pressure, over the whole concentration range. The corresponding excess molar volumes were computed from the experimental data. The results were fitted by means of the Nagata equation, such parameters being gathered. Simple mixing rules were applied into cubic equations of state (EOS) of two parameters for prediction, only a qualitative agreement between the experimental and theoretical values both in magnitude and sign being obtained, due to the high non-ideal trend of mixtures.

Isothermal vapor-liquid equilibrium for the ternary mixtures 2-methyl-1-propanol + n-hexane + 1-chlorobutane and 2-methyl-2-propanol + n-hexane + 1-chlorobutane and for the binary mixtures 2-methyl-1-propanol + n-hexane and 2-methyl-2-propanol + n-hexane have been studied at T ) 298.15 K. The experimental data were checked for thermodynamic consistency using the method of van Ness. The isothermal vapor-liquid equilibrium data of the ternary mixtures together with the corresponding constituent binary mixtures were correlated with the Wilson equation. The G E values obtained have been compared with those of the ternary mixtures 1-butanol or 2-butanol + n-hexane + 1-chlorobutane previously investigated. Figure 3.

The activity coefficients were found to be thermodynamically consistent and were satisfactorily correlated with the Margules, van Laar, Wilson, NRTL and UNIQUAC equations. They have been also compared with the results obtained from the application of ASOG and the modified UNIFAC group contribution methods.

Densities ρ of the 1-butanol + chloroform + benzene ternary mixture and the 1-butanol + chloroform and 1-butanol + benzene binaries have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K and atmospheric pressure, using an oscillating U-tube densimeter. From these densities, excess molar volumes (V E ) were calculated and fitted to the Redlich-Kister equation for all binary mixtures and to the Nagata and Tamura equation for the ternary system. The Radojković et al. equation has been used to predict excess molar volumes of the ternary mixtures. Also, V E data of the binary systems were correlated by the van der Waals (vdW1) and Twu-Coon-Bluck-Tilton (TCBT) mixing rules coupled with the Peng-Robinson-Stryjek-Vera (PRSV) equation of state. The prediction and correlation of V E data for the ternary system were performed by the same models.

Densities of the ternary mixtures chlorobenzene+n-hexane+(n-undecane or n-dodecane) have been measured at 298.15 K and atmospheric pressure. The excess molar volumes were computed from the experimental data and were fitted to the Nagata equation. The partial excess molar volumes were calculated, an interpretation in terms of composition and molecular size being made. The molecular radius was derived and compared from different thermodynamic property and models. The Peng–Robinson and Soave–Redlich–Kwong equations of state were applied, in combination with different mixing rules for excess molar volume prediction. The accurate obtained results by means of cubic equations of state show the applicability of binary interaction

Densities of the quaternary mixture consisting of {1-chlorobutane (1) + 2-chlorobutane (2) + butylamine (3) + butylacetate (4)} and related ternary mixtures of {1-chlorobutane (1) + 2-chlorobutane (2) + butylamine (3)}, {1-chlorobutane (1) + 2-chlorobutane (2) + butylacetate (4)}, {2-chlorobutane (2) + butylamine (3) + butylacetate (4)}, and binary systems of {1-chlorobutane (1) + 2-chlorobutane (2)}, {2-chlorobutane (2) + butylamine (3)}, were measured over the whole range of composition at T = 298.15 K and ambient pressure. Excess molar volumes, V E m , for the mixtures were derived and correlated as a function of mole fraction by using the Redlich-Kister and the Cibulka equations for binary and ternary mixtures, respectively. From the experimental data, partial molar volumes, V m,i and excess partial molar volumes, V E m;i were also calculated for binary systems. The experimental results of the constituted binary mixtures have been used to test the applicability of the Prigogine-Flory-Paterson (PFP) theory. A number of geometrical and empirical equations were also used to verify their ability to predict ternary and quaternary properties from their lower order mixtures. The experimental data were used to evaluate the nature and type of intermolecular interactions in multi-component mixtures.

Densities of four binary mixtures formed by an isomer of chlorobutane (1-chlorobutane, 2-chlorobutane, 1-chloro-2methylpropane, or 2-chloro-2-methylpropane) and methyl tert-butyl ether have been measured in the temperature range 283.15 KÀ 313.15 K; from these densities the corresponding excess volumes have been obtained and correlated. The isothermal vaporÀ liquid equilibria have been also studied at T = 288.15, 298.15, and 308.15 K, and the experimental data have been satisfactorily checked for thermodynamic consistency using the method of Van Ness. The isothermal vaporÀliquid equilibria data have been correlated using the Wilson equation, and excess Gibbs energies have been calculated. We have employed this experimental information to check the reliability of the predicted densities and vaporÀliquid equilibria of the volume translated PengÀRobinson group contribution equation of state (VTPR model) by comparing the experimental results with the corresponding predictions. The predictions of both properties can be considered as satisfactory.
