  • Isobaric Vapor−Liquid Equilibria of the Ternary System Pentan-1-ol + Pentyl Acetate + Nonane
    Journal of Chemical & Engineering Data, 2011
    Co-Authors: Helle Kirss, M. Kuus, Enn Siimer
    Abstract:

    Isobaric vapor−liquid equilibria (VLE) were measured for the ternary system pentan-1-ol + Pentyl Acetate + nonane and for one constituent binary system, pentan-1-ol + Pentyl Acetate, at the pressures (26.66, 53.33, 79.99, and 101.32) kPa. Boiling temperature (T)−liquid composition (x) relations were obtained by using a semimicroebulliometer. The Wilson equation was used to correlate the binary T−x data and to predict VLE in the ternary system.

  • surface and interfacial tensions of the systems water n butyl Acetate methanol and water n Pentyl Acetate methanol at 303 15 k
    Fluid Phase Equilibria, 2003
    Co-Authors: B.m.s Santos, Abel G.m. Ferreira, Isabel Fonseca
    Abstract:

    Abstract The surface tension in the homogeneous domain of the ternary liquid mixtures water + n-butyl Acetate + methanol and water + n-Pentyl Acetate + methanol as well as of the constituent binaries has been measured at 303.15 K and atmospheric pressure. The respective excess surface tension was correlated as a function of the composition using empirical and thermodynamic-based relations. The liquid interfacial tension was measured in the liquid–liquid equilibrium range at the same conditions of temperature and pressure. A new equation is proposed to correlate the excess surface tension of binary mixtures. This equation can be obtained from the Butler equation and correlates well the excess surface tension data. The prediction of the surface tension of the binary and ternary systems has been made using the Sprow and Prausnitz model. The Fu et al. and Li et al. models were also applied to predict that property in the ternary systems. The liquid interfacial tension of the ternary systems was correlated and predicted using the relations proposed by Li and Fu and Fu et al., respectively, with satisfactory results.

  • viscosity and density data of the system water n Pentyl Acetate methanol calculations with a modified redlich kwong soave equation of state
    Fluid Phase Equilibria, 2003
    Co-Authors: F Giro, M.f Gonçalves, Abel G.m. Ferreira, Isabel Fonseca
    Abstract:

    Abstract The viscosities and the densities of the ternary mixtures water+n-Pentyl Acetate+methanol and those of the constituent binaries have been measured at 303.15 K and atmospheric pressure in the homogeneous region. The respective viscosity deviations and excess molar volumes were fitted to a Redlich–Kister (RK) type equation. A modified Redlich–Kwong–Soave equation of state due to Fuller was used with the Eyring kinematic viscosity model to correlate viscosities of binary data. The equation of state constants were calculated using the van der Waals one-fluid mixing rules with the cross-parameters, aij, obtained with the classical and a two-parameter Redlich–Kister combining rules. The new model correlates the viscosity of the binaries with an average absolute deviation

  • isobaric vapor liquid equilibria for water acetic acid n Pentyl Acetate or isopropyl Acetate
    Journal of Chemical & Engineering Data, 2005
    Co-Authors: Weixian Chang, Guofeng Guan, Huqing Yao
    Abstract:

    Isobaric vapor−liquid equilibria (VLE) data for water + acetic acid, acetic acid + isopropyl Acetate, acetic acid + n-Pentyl Acetate, water + acetic acid + isopropyl Acetate, and water + acetic acid + n-Pentyl Acetate systems have been measured at 101.33 kPa using a recirculating still. The nonideality of the vapor phase caused by the association of the acetic acid has been corrected by the Hayden−O'Connell method. The three experimental binary data have been correlated by the NRTL and UNIQUAC models. The obtained NRTL model parameters from binary data have been used to predict ternary VLE data. The ternary predicted values obtained in this way agree well with the experimental values.
