Salting-out of triethylphosphate by inorganic electrolytes

Abstract

. Can. J. Chem. 62, 81 (1984). The salting-out of triethylphosphate (TEP) from water was measured at 25°C for twelve inorganic electrolytes. If salting out is taken as an additive property of ions, then the effectiveness for salting TEP out of water is I-< Br-< C1-< +SO:-< $0:-for anions and $La3+ < Na+ .= NH: < Cs+ < $aZ+ = $~g " < K' < i~a " for cations. The results were fitted to three theories. The distribution theory of Conway, Desnoyers, and Smith predicts the order of magnitude of the experimental results, but does not discriminate well between salts of the same valence type. The electrostriction theory of McDevit and Long discriminates well between ions but gives results three or five times larger than those observed. Scaled particle theory predicts the results reasonably well, but the predictions depend critically on the choice of ionic and molecular parameters. Thus, none of these theories is entirely satisfactory.

Effect of Inorganic Salts on the Isobaric Vapor–Liquid Equilibrium of the Ethyl Acetate–Ethanol System

“…Numerous experimental investigations have been performed on the application of scaled particle theory to calculate the salting coefficient of nonpolar aqueous systems. , The salting coefficients of organic and inorganic electrolyte solutions of nonpolar systems were found to be in good agreement with experimental results. In recent years, scaled particle theory has also been applied to the case of polar systems in aqueous media, − and a reasonable agreement with experimental data was observed.…”
