  • Isothermal Vapor−Liquid Equilibrium of Ternary Mixtures Containing 2-Methyl-1-propanol or 2-Methyl-2-propanol, n-Hexane, and 1-Chlorobutane at 298.15 K
    Journal of Chemical & Engineering Data, 2010
    Co-Authors: Hernando Guerrero, Carlos Lafuente, Ignacio Giner, Héctor Artigas, Ignacio Gascón
    Abstract:

    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

  • Isobaric Vapor−Liquid Equilibrium for the Binary Mixtures (2-Butanol + n-Hexane) and (2-Butanol + 1-Butylamine) and for the Ternary System (2-Butanol + n-Hexane + 1-Butylamine) at 101.3 kPa
    Journal of Chemical & Engineering Data, 2002
    Co-Authors: M. Domínguez, Héctor Artigas, Santiago Martín, And M. Carmen López, Félix M. Royo
    Abstract:

    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 found to be thermodynamically consistent, and they were satisfactorily correlated with the Margules, van Laar, Wilson, NRTL, and UNIQUAC equations. 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.

  • Speed of sound and isentropic compressibility of the ternary mixture (2-Butanol + n-Hexane + 1-Butylamine) and the constituent binary mixtures at 298.15 K and 313.15 K
    Journal of Molecular Liquids, 2000
    Co-Authors: M. Domínguez, Héctor Artigas, Pilar Cea, María C. López, José S. Urieta
    Abstract:

    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, 1998
    Co-Authors: M. Domínguez, Héctor Artigas, Ana M. Mainar, J. Santafé, José S. Urieta
    Abstract:

    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.

  • Isobaric VLE Data of the Ternary System (1-Butanol + n-Hexane + 1-Butylamine) and the Three Constituent Binary Mixtures at 101.3 kPa
    JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1997
    Co-Authors: M. Domínguez, Héctor Artigas, Ana M. Mainar, Félix M. Royo, José S. Urieta
    Abstract:

    The isobaric vapour-liquid equilibrium has been experimentally studied for the ternary mixture (1-butanol + n-hexane + 1-butylamine) and for the binary mixtures (1-butanol + n-hexane), (1-butanol + 1-butylamine), and (n-hexane + 1-butylamine) at 101.3 kPa. The activity coefficients were found to be thermodynamically consistent and they 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.

  • Surface Tensions of the Ternary Mixtures Containing an Isomeric Butanol + n-Hexane + 1-Chlorobutane at 298.15 K
    Journal of Chemical & Engineering Data, 2010
    Co-Authors: Montserrat Pérez-navarro, Ignacio Gascón, Isabel Bandrés, Ignacio Giner, Carlos Lafuente
    Abstract:

    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. From these experimental data, surface tension deviations were calculated and fitted by the Cibulka’s equation. Experimental results have been compared to the predictions obtained by a group contribution method; furthermore, using this method, the excess surface molar compositions of n-hexane in the ternary mixtures have been also estimated.

    The Journal of Chemical Thermodynamics, 2009
    Co-Authors: S. Martínez, Carlos Lafuente, Isabel Bandrés, Luz M. Ballesteros, Ignacio Gascón
    Abstract:

    Abstract Isothermal (vapour + liquid) equilibrium data for the ternary mixtures 1-butanol + n-hexane + 1-chlorobutane and 2-butanol + n-hexane + 1-chlorobutane have been studied with a recirculating still at T  = 298.15 K. The experimental data were satisfactorily checked for thermodynamic consistency using the method of van Ness. Activity coefficients and excess Gibbs function have been correlated with the Wilson equation. The G E values obtained for the two ternary systems are very similar.

  • Refractive Indices of the Ternary Mixtures Butanol + n -Hexane + 1-Chlorobutane
    Journal of Solution Chemistry, 2008
    Co-Authors: Montserrat Pérez-navarro, Ignacio Gascón, Gorka Pera, Marta Haro, Carlos Lafuente
    Abstract:

    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.
