  • 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.

  • Consistency test for VLE data of salt-containing system at fixed Liquid Composition
    Fluid Phase Equilibria, 2004
    Co-Authors: Ren Yi Sun, Qian Sun
    Abstract:

    Abstract The activity coefficient of salt in mixed solvents was expressed as a function of VLE data of salt-containing system by using the ternary Gibbs–Duhem equation. Two criteria for testing salt data in VLE at fixed Liquid Composition were proposed based on thermodynamics and the common character of electrolytic activity coefficients. According to the criteria a method for testing VLE data of salt-containing system at fixed Liquid Composition was suggested. The quality of a data group as a whole can be evaluated by this method, and some wrong data can be indicated. The method presented in this paper is not only severe in theory, but simple and convenient in application.

  • Effect of nonvolatile solute on vapor–Liquid equilibrium at fixed Liquid Composition
    Fluid Phase Equilibria, 2001
    Co-Authors: Ren Yi Sun, Qian Sun
    Abstract:

    Abstract The influence of some nonvolatile solutes on boiling points of two azeotropic mixtures (1-propanol–water and methanol–tetrahydrofuran systems) was determined by means of isobaric vapor–Liquid equilibrium experiments. A basic thermodynamic equation of nonvolatile solute effect on vapor–Liquid equilibrium at fixed Liquid Composition was derived. Based on the theoretical analysis about the equation, two criterions of universal significance were obtained: (1) when a little nonvolatile solute dissolves in a binary Liquid mixture with constant Composition, if the vapor Composition of less volatile component is increased the boiling point must be elevated at given pressure or the vapor pressure must be depressed at given temperature; (2) when a little nonvolatile solute dissolves in an azeotropic mixture, any kind of nonvolatile solute always causes the elevation of boiling point at given pressure or the depression of vapor pressure at given temperature irrespective of the variation of vapor Composition. Verifying through the experiments of this paper and lot of the relevant experimental data in the literature, all of the experimental results were in agreement with both criterions without exception.
