Theoretical and experimental investigations of fluctuation thermodynamic properties of liquid solutions
Abstract
Work has proceeded in the three areas of theory, correlation and experiment. The theoretical analyses have focussed on the statistical mechanical basis for the successful method for correlating liquidphase activity coefficients of complex mixtures called solution of groups where the system is viewed as a mixture of groups rather than molecules and binary parameters are catalogued for the relatively small number of groups that make up the many molecules of petrochemical processing interest. From a correlation point of view, we have established a unique and simple form for the partial molar volume at infinite dilution of strong salts (e.g., NaCl) in water for all pressures and temperatures up to 350 C. In experiment, we have performed an analysis of the use of Rayleigh light scattering as a technique for obtaining thermodynamic properties of liquid mixtures.
