    Chemical kinetics at a critical point (1973)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 19 (1973), S. 1126-1133 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The rate of the Diels-Alder reaction of isoprene with maleic anhydride has been measured in the vicinity of the upper critical solution points of two liquid-liquid mixtures, and the rate of the Menschutkin reaction of ethyl iodide and triethylamine has been investigated near a lower critical solution point. Anomalous behavior has been observed, with the former reaction rate augmented by up to 40% and the latter apparently running 25-30% too slow. A possible explanation for these results is presented in terms of transition state theory and the abrupt behavior of the solution activities of dilute solutes near a critical point.

    STICT model for surface thermodynamics of liquid metal solutions (1987)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 33 (1987), S. 1612-1619 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Notes: A new model, called STICT for surface thermodynamics using ideal chemical theory, is developed for the surface tension of liquid metal alloys. It uses the Guggenheim approach to relate surface phase properties to those in the bulk. For strongly solvated metal mixtures, ideal chemical theory is used to characterize bulk properties. The STICT model fits experimental data well for the seven systems for which sufficient data exist. Moreover, calculations of bulk and surface true compositions give some guidance to the tailoring of the surface properties of alloys for various applications.

    A chemical theory for the thermodynamics of highly-solvated liquid metal mixtures (1982)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 28 (1982), S. 325-333 
    Details
    ISSN: 0001-1541

    Notes: Chemical solution theory has been shown to be particularly well-suited for certain classes of liquid metal mixtures. A generalized formulation of this approach is presented and it eliminates the need for mechanistic information. The results are in good agreement with many data, and could lead to a variety of industrial applications of liquid metal solvents.

    Analytical model for excess Gibbs energy of nonspecific liquid metal interactions (1984)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 30 (1984), S. 143-150 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: A physical model for the very strong intermolecular forces in liquid metal mixtures is proposed, involving the combined effects of ion-ion, ion-electron, and electron-electron interactions plus the charge density effects on the electron kinetic energy. The resulting excess Gibbs energy expression contains a single cross-energy parameter which must be evaluated either from the eutectic point or from one mixture datum. The applicability of the model is limited to systems without strong specific solvation, but it does effectively predict both negative and positive deviations from Raoult's law, including the asymmetry arising from size differences. Applications are shown for vapor-liquid, liquid-liquid and solid-liquid equilibria.

    NMR Measurements of chemical theory equilibrium constants for hydrogen-bonded solutions (1986)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 32 (1986), S. 820-828

    ISSN: 0001-1541

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Although various chemical theories have often been used to characterize hydrogen-bonded systems with some success, they have been limited by the fact that the equilibrium constants were adjustable parameters. This paper reports a method to measure directly these constants by proton nuclear magnetic resonance spectroscopy. Results are reported for several systems and are used with a chemical-physical theory to predict vapor-liquid equilibria.

    Phase equilibria for strongly nonideal liquid mixtures at low temperatures (1965)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 11 (1965), S. 886-890

    ISSN: 0001-1541

    Notes: Investigation of the nonideal behavior of mixtures of simple molecules is an important step toward improved understanding of the theory of solutions. This work describes an equilibrium apparatus suitable for the measurement of vapor-liquid and vapor-liquid-liquid equilibria of simple fluid mixtures at cryogenic temperatures. Vapor-liquid data are reported for the argonethane and nitrogen-carbon tetrafluoride systems. Contrary to expectations, limited liquid-phase miscibility was not observed for either of these mixtures. These results and those for other nonideal mixtures of simple molecules are compared with predictions of upper critical solution temperatures by the theory of regular solutions. Usefulness of this theory is impaired by its neglect of the order-disorder phenomenon and, more seriously, by the geometric-mean assumption for the intermolecular forces between dissimilar molecules.

    Measurement and application of limiting activity coefficients (1981)

    Notes: Infinite dilution activity coefficients (γ∞) in binary liquid mixtures are data of wide practical and theoretical applicability, but their extensive use has been hindered by the experimental limitations of classical vapor-liquid equilibrium techniques. Two new experimental methods for accurate γ∞ determinations are presented. These techniques, both faster and more accurate than classical methods, are complementary, and their applicability to different types of binary systems is discussed.

    Notes: Molecular thermodynamics is used to develop a new model for the prediction of the thermodynamic properties of liquid metal mixtures. It combines corresponding states theory with a perturbed hard sphere model to predict successfully, without adjustable parameters, a variety of mixture properties from pure component properties for simple eutectic mixtures.

    Statistical surface thermodynamics of simple liquid mixtures (1964)

    Notes: The surface properties of nonpolar liquid mixtures are derived from the application of the grand partition function to a cell model of the vapor-liquid interface. The surface tension and surface composition are expressed in terms of the activity coefficients in the bulk liquid and pure-component properties. The results are in excellent agreement with existing data for the surface tension of mixtures. This treatment provides a sound theoretical basis for the prediction of surface properties of other liquid systems and is especially applicable to cryogenic mixtures.
