Measurement and correlation of the solubilities of 2 - [(6- Oxido - 6H - dibenz [c,e] [1,2] oxaphosphorin - 6 - yl) methyl] butanedioic acid in selected solvents / Xian-Zhao Shao in Industrial & engineering chemistry research, Vol. 51 N° 13 (Avril 2012)

The measurements were carried out over the temperature range from 293 to 353 K in methanol, ethanol, 1-propanol, tetrahydrofuran, 1,4-dioxane, ethyl acetate, toluene, benzene, and cyclohexane. Several commonly used thermodynamic models, including the empirical equation and the Scatchard–Hildebrand, Wilson, nonrandom two-liquid, and UNIQUAC equations, were applied to correlate the experimental solubility data. The binary interaction parameters of the above models were found to have a linear dependence on the temperature, and the coefficients were regressed. It was found that all of these models can satisfactorily reproduce the experimental data and the UNIQUAC equation can provide the best correlation results with an overall relative standard deviation of 1.52%.

Thermodynamics of phase equilibria in aqueous strong electrolyte systems / Mi-Yi Li in Industrial & engineering chemistry research, Vol. 50 N° 6 (Mars 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 6 (Mars 2011) . - pp. 3621-3631 Titre : Thermodynamics of phase equilibria in aqueous strong electrolyte systems Type de document : texte imprimé Auteurs : Mi-Yi Li, Auteur ; Li-Sheng Wang, Auteur ; Jürgen Gmehling, Auteur Année de publication : 2011 Article en page(s) : pp. 3621-3631 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Strong  electrolyte  Phase  equilibrium Résumé : The middle range (MR) parameters of the LIQUAC model were improved as a function of temperature to allow the calculation of the activities of all the species in the solution over a wide temperature and concentration range. New parameters were recorrelated by using the experimental data of osmotic coefficients, vapor-liquid equilibria (VLE), mean ion activity coefficients and salt solubilities from the Dortmund Data Bank (DDB). The coordinates of the eutectics, the peritectics, and the ice-water equilibria of the aqueous electrolyte systems were represented with the model. Standard Gibbs energies of formation, standard enthalpies of formation, and heat capacities of various solids were retrieved from the fitting of their solubility products with respect to temperature or estimated using the group contribution method. The schematic phase diagrams for the salts in aqueous systems are presented in this work. A good agreement of calculated results with the published measurements is observed.
