Thermodynamically consistent equations for the accurate description of the logarithm of the solvent activity and related properties of electrolyte solutions with a unique set of parameters. Critical analysis of the mean activity coefficient evaluation
(Springer/Plenum Publishers, 2020-05)
Thermodynamically consistent equations for the accurate description of the dependence on concentration of the properties of electrolyte solutions are proposed, based on a polynomial of order i/4 and a unique set of adjustable ...
Tracer diffusion and activity coefficients of counterions in aqueous solutions of polyelectrolytes
(1969)
Tracer diffusion coefficients of Ag+ in silver polystyrenesulfonate and counterion activity coefficients of sodium and silver polystyrenesulfonates have been determined at different concentrations. The results have been ...
Ionic medium effects on equilibrium constants .1. Proton, copper(II), cadmium(II), lead(II) and acetate activity coefficients in aqueous solution
(Elsevier B.V., 1996-10-01)
The molar single ion activity coefficients associated with hydrogen, copper(II), cadmium(II) and lead(II) ions were determined at 25 degrees C and ionic strengths between 0.100 and 3.00 M (NaClO4), whereas for acetate the ...
Calculation and prediction of multicomponent azeotropes with activity coefficient modelsCálculo y predicción de azeótropos multicomponentes con modelos de coeficientes de actividad
(Centro de Informacion Tecnologica, 2008-05)
This paper studies the multicomponent azeotropic capacity prediction of activity coefficient models. Wilson and UNIFAC models are used for homogeneous azeotropes while UNIQUAC and UNIFAC models are used for heterogeneous ...
Infinite dilution activity coefficients in mono-, di-, and tripalmitin and palmitic acid
(American Chemical Society, 1996-09)
Infinite dilution activity coefficients of several organic solutes in mono-, di-, and tripalmitin and in palmitic acid were measured by gas chromatography, at temperatures between 353 K and 373 K. The solutes include ...
Infinite dilution activity coefficients of solvents in fatty oil derivatives
(Planta Piloto de Ingeniería Química, 2003-06)
Inverse gas-liquid chromatography has been applied to measure infinite dilution activity coefficients (γ ∞) of different solutes in low and high molecular weight triacylglycerides (TAGs) and in mixtures of carboxylic acids ...
