  • (Vapour + liquid) equilibria for the binary mixtures (1-propanol + Dibromomethane, or + bromochloromethane, or + 1,2-dichloroethane or + 1-bromo-2-chloroethane) at T = 313.15 K

    Abstract:

    Abstract Isothermal (vapour + liquid) equilibria (VLE) at 313.15 K have been measured for liquid 1-propanol + Dibromomethane, or + bromochloromethane or + 1,2-dichloroethane or + 1-bromo-2-chloroethane mixtures. The VLE data were reduced using the Redlich–Kister equation taking into consideration the vapour phase imperfection in terms of the 2nd molar virial coefficients. The excess molar Gibbs free energies of all the studied mixtures are positive and ranging from 794 J · mol−1 for (1-propanol + bromochloromethane) and 1052 J · mol−1 for (1-propanol + 1-bromo-2-chloroethane), at x = 0.5. The experimental results are compared with modified UNIFAC predictions.

    Abstract:

    Abstract In this paper, the isothermal vapour–liquid equilibrium (VLE) at T = 308.15 K have been measured for liquid binary systems Dibromomethane + n-heptane, bromotrichloromethane + n-heptane, bromotrichloromethane + Dibromomethane, bromotrichloromethane + bromochloromethane and Dibromomethane + bromochloromethane by a dynamic method. The VLE data have been reduced using the Redlich–Kister equation taking into consideration the vapour phase imperfection in terms of 2nd molar virial coefficients and molar excess Gibbs energies, G m E , have been calculated. The experimental G m E is positive for all systems presenting the greatest value for Dibromomethane + n-heptane and a negligible value for Dibromomethane + bromochloromethane system. From our experimental data and those reported in the literature, phase and volumetric behaviour of the binary systems containing Dibromomethane, bromochloromethane, bromotrichloromethane or n-heptane have been modelled. Two equations of state, EoS, of different formulation have been used obtaining a good agreement for all systems. The mean relative deviations for the studied properties are MRD (P) = 1.57%, AAD (y) = 0.0116 and MRD (ρ) = 0.55% for Peng–Robinson EoS, and MRD (P) = 1.20%, AAD (y) = 0.0093 and MRD (ρ) = 0.38% for PC-SAFT EoS.

  • isothermal vapor liquid equilibria of ethyl acetate Dibromomethane or bromochloromethane or 1 2 dichloroethane or 1 bromo 2 chloroethane at t 313 15 k

    Co-Authors: Pilar Garciagimenez, Jose Munoz Embid, Manuela Artal, Vanesa Gilhernandez, Santos Otin
    Abstract:

    Isothermal vapor−liquid equilibria (VLE) at 313.15 K have been measured for liquid ethyl acetate + Dibromomethane or + bromochloromethane or + 1,2-dichloroethane or + 1-bromo-2-chloroethane mixtures. The VLE data were reduced using the Redlich−Kister equation by taking into consideration the vapor-phase nonideality in terms of the second molar virial coefficients, and the liquid activity coefficients were correlated by means of the Margules, van Laar, Wilson, NRTL, and UNIQUAC equations. The thermodynamic consistency of the experimental data was checked by means of the test of Van Ness et al. in the version of Fredenslund et al. The excess molar Gibbs energies of all of the studied mixtures are negative and range from −75 J mol-1 for ethyl acetate + 1-bromo-2-chloroethane to −300 J mol-1 for ethyl acetate + bromochloromethane at a mole fraction of x = 0.5.
