  • (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
    The Journal of Chemical Thermodynamics, 2020
    Co-Authors: Vanesa Gil-hernandez, Manuela Artal, Santos Otin, Pilar García-giménez, Inmaculada Velasco
    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.

  • Temperature and pressure dependence of the volumetric properties of binary liquid mixtures containing 1-propanol and dihaloalkanes
    Physics and Chemistry of Liquids, 2005
    Co-Authors: Vanesa Gil-hernandez, Manuela Artal, Jose Munoz Embid, Pilar García-giménez, Inmaculada Velasco
    Abstract:

    Densities of 1-propanol + dibromomethane, or +Bromochloromethane, or +1,2-dichloroethane, or +1-bromo-2-chloroethane binary mixtures were measured at 288.15, 298.15 and 308.15 K, over the entire composition range. Thermal expansion coefficients, α, and excess molar volumes, , were calculated. Moreover, densities at 298.15 K and pressures up to 2 × 107 Pa were determined for the same mixtures. Isothermal compressibilities, κT, of the pure liquids and their mixtures were obtained.
