Excess Gibbs energies of mixing for some binary mixtures
Journal of Chemical & Engineering Data, 1975Mefhod. Benzene, n-hexane, pyridine, chloroform, and bromoform were purified as suggested by Vogel (9). Purities of the final samples were checked by measuring their densities; the results agreed to within 0.00002 g cm-3 with those in the literature as reported earlier (6). Vapor pressures were measured by a modified static method (7).

The Excess Molar Gibbs Energy of Nuclidic Liquid Mixtures
Berichte der Bunsengesellschaft für physikalische Chemie, 1995AbstractThe calculation of GmE from VLE measurements has been extended to multicomponent systems including those where chemical reactions can occur. For nuclide mixtures, the methods have to be adapted in order to take into account the similarity of the mixture's components and the pseudo‐multicomponent characteristics of a system with isotopic ...

The excess gibbs free energy of aqueous nonelectrolyte solutions
AIChE Journal, 1988AbstractA new thermodynamic model is presented for aqueous solutions of polar nonelectrolytes. The model is based on solute aggregation in an aqueous lattice, which is inferred from spectroscopic, thermodynamic, and physiochemical data. The adjustable model parameters have physical meaning, and are less intercorrelated and temperature‐dependent than ...

The Excess Gibbs Free Energies of Chloroethanes with sec-Butanol
Physics and Chemistry of Liquids, 1988Abstract Isobaric boiling point data for systems of 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2,2-tetrachloroethane, and sec-butanol have been measured over the whole composition range at 300, 500 and 700 mmHg. The experimental t-x data have been used to predict Wilson parameters and equilibrium vapor compositions.

Thermodynamics of weak interactions: excess enthalpies and excess Gibbs free energies of mixing
Thermochimica Acta, 1975Abstract Excess enthalpies of chloroform + n-hexane, bromoform + n-hexane, bromoform + pyridine and bromoform + benzene and excess Gibbs free energies of mixing for bromoform + pyridine, chloroform + pyridine, bromoform + n-hexane, chloroform + n-hexane and bromoform + benzene have been determined at 308.15 K and the same factors have been examined ...

AbstractThe rapid measurement of static vapour pressures of binary liquid mixtures as a function of composition by a new continuous‐dilution apparatus is described. These measurements, together with the computed excess Gibbs free energies, are reported for mixtures of benzene and 1,1,2‐trichlorotrifluoroethane at 283.30, 287.83, 293.21, 298.21, 303.06 ...

The excess enthalpies of mixtures of 2,3-dimethylbutane+cyclo-octane have been measured at 288.15, 298.15, and 313.15 K with an isothermal displacement calorimeter. The excess volumes have been measured at the same temperatures with a dilution dilatometer.

Excess enthalpies, excess volumes, and excess Gibbs free energies are reported over the entire composition range for n-hexane + n-undecane at 298.15 and 308.15 K. HE was obtained with an isothermal mercury-displacement calorimeter, VE with a continuous dilution dilatometer, and GE is calculated from vapor-pressure measurements made with a continuous ...
