Journal of Molecular Liquids, 2000Co-Authors: M. Domínguez, Héctor Artigas, Pilar Cea, María C. López, José S. UrietaAbstract:Abstract Densities and speeds of sound for (2-Butanol + n -Hexane + 1-Butylamine) at 298.15K and 313.15 K, and the constituent binary mixtures (2-Butanol + n -Hexane), (2-Butanol + 1-Butylamine) at 298.15 K and 313.15 K, and ( n -Hexane + 1-Butylamine), at 313.15 K have been measured. The isentropic compressibilities, the excess isentropic compressibilities, and the speeds of sound deviations have been calculated for both the binary and the ternary systems, from the experimental data. The isentropic compressibilities have been compared with calculated values from the Free Length Theory (FLT) and Collision Factor Theory (CFT).

Densities and excess molar volumes of the ternary mixture (1-butanol + n-hexane + 1-chlorobutane) at 298.15 and 313.15 K. Application of the ERAS model
Fluid Phase Equilibria, 1998Co-Authors: M. Domínguez, Héctor Artigas, Ana M. Mainar, J. Santafé, José S. UrietaAbstract:Abstract Densities of the liquid mixtures (n-hexane+1-chlorobutane) and (1-butanol+n-hexane+1-chlorobutane) have been measured by the vibrating tube technique at 298.15 K and 313.15 K. With these densities, excess molar volumes were calculated. An extended version of the so-called ERAS model has been used for describing VE of the complete ternary system at 298.15 K. Qualitatively the ERAS-model gives an adequate representation of this system, being similar the shapes of both the experimental and the predicted curves.

Viscosities of the ternary mixture (1-butanol + n-hexane + 1-butylamine) at the temperatures 298.15 and 313.15 K
Fluid Phase Equilibria, 1996Co-Authors: M. Domínguez, Félix M. Royo, Juan I. Pardo, María C. López, José S. UrietaAbstract:Abstract Viscosities of the ternary mixture {1-butanol + n -hexane + 1-butylamine} and the binary mixtures {1-butanol + n -hexane}, {1-butanol + 1-butylamine} and { n -hexane + 1-butylamine} have been measured at 298.15 and 313.15 K. Viscosity deviations for the binary and ternary systems were fitted to Redlich-Kister's and Cibulka's equations, respectively. The “viscosity-thermodynamic” model (UNIMOD) has been used to correlate experimental data for the binary mixtures and to predict the viscosities for the ternary system. The Group-Contribution Thermodynamic-Viscosity model (GC-UNIMOD), and the group contribution method proposed by Wu have been used to predict the viscosity of the binary and ternary systems.

Journal of Chemical & Engineering Data, 2002Co-Authors: M. Domínguez, Héctor Artigas, Santiago Martín, And M. Carmen López, Félix M. RoyoAbstract:Isobaric vapor−liquid equilibrium has been experimentally studied for the binary mixtures 2-butanol + n-hexane and 2-butanol + 1-butylamine and for the ternary mixture 2-butanol + n-hexane + 1-butylamine at 101.3 kPa.

The activity coefficients were also compared with the results obtained from the application of the ASOG and modified UNIFAC group contribution methods. The boiling points of the solutions were correlated with compositions by the Wisniak−Tamir equations. The results obtained indicate that the binary system 2-butanol + n-hexane deviates positively from ideality, whereas 2-butanol + 1-butylamine deviates negatively from ideality. The ternary system deviates positively or negatively depending on the composition. Only the binary systems present azeotropy. Azeotropic behavior was not found in the ternary mixture.

Journal of Chemical & Engineering Data, 2010Co-Authors: Hernando Guerrero, Carlos Lafuente, Ignacio Giner, Héctor Artigas, Ignacio GascónAbstract: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-methyl1-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. The study of vapor-liquid equilibrium (VLE) of multicomponent liquid mixtures in isothermal conditions provides experimental data of great interest in thermodynamics and chemical engineering and contributes decisively for the development of accurate methods to predict and correlate phase equilibrium. However, relatively few investigations on isothermal VLE of ternary mixtures can be found in the literature. In the past years, our laboratory has been involved in the study of several thermodynamic and transport properties of the ternary mixtures containing an isomer of butanol + n-hexane + 1-chlorobutane, 1-7 and we also have recently reported isothermal VLE data for the ternary systems 1-butanol or 2-butanol + n-hexane + 1-chlorobutane at 298.15 K. 8 To complete this systematic study, we report here vapor-liquid equilibrium data obtained at 298.15 K for the ternary systems 2-methyl-1-propanol or 2-methyl-2-propanol + n-hexane + 1-chlorobutane and for the binary mixtures 2-methyl-1-propanol or 2-methyl-2-propanol + n-hexane. Thermodynamic consistency of the experimental data has been checked by the method of van Ness. 9 We have also correlated activity coefficients of the components and excess Gibbs function of the mixtures using the Wilson equation. 10

Journal of Chemical & Engineering Data, 2010Co-Authors: Montserrat Pérez-navarro, Ignacio Gascón, Isabel Bandrés, Ignacio Giner, Carlos LafuenteAbstract:Surface tensions of the ternary mixtures containing an isomer of butanol (1-butanol, 2-butanol, 2-methyl-1-propanol, or 2-methyl-2-propanol) + n-hexane + 1-chlorobutane have been measured at atmospheric pressure and 298.15 K.

Refractive Indices of the Ternary Mixtures Butanol + n -Hexane + 1-Chlorobutane
Journal of Solution Chemistry, 2008Co-Authors: Montserrat Pérez-navarro, Ignacio Gascón, Gorka Pera, Marta Haro, Carlos LafuenteAbstract:Refractive indices for the ternary mixtures formed by each one of the isomers of butanol (1-butanol, 2-butanol, 2-methyl-1-propanol and 2-methyl-2-propanol), with n-hexane and 1-chlorobutane, have been measured at 298.15 K. From these data the refractive index deviations were calculated and fitted by Cibulka’s equation, and the refractive index deviations were related to the corresponding excess volumes of the mixtures. Furthermore, several mixing rules were used to predict both refractive indices and excess volumes of the ternary mixtures from their densities or refractive indices.
