Abstract

It is demonstrated that the Debye-Hückel (D-H) term when applied to single electrolyte-binary solvent mixtures predicts salting in when salting out is observed. An empirical extension of the D-H term is proposed that eliminates this problem. When combined with an NRTL term to account for the long-range forces, the resulting expression provides successful correlation of meanionic activity coefficients and vapor-phase compositions of several ternary systems. Prediction results for y±are in the right direction, but vapor-phase compositions do not reflect the electrolyte effect. © 1987, American Chemical Society. All rights reserved.
