Salt effects on liquid-liquid equilibria in the partially miscible systemswater+2-butanone and water plus ethyl acetate

Liquid-liquid equilibrium data for the partially miscible systems of water + 2-butanone + salt and water + ethyl acetate + salt were measured at 298.1 5 K. The salts used were potassium iodide, sodium bromide and lithium chlor ide. The systems were compared in terms of salting effect. The three-contri bution electrolyte NRTL model is used to perform the data regression of the experimental data. New binary parameters are obtained. The calculated resu lts are compared with the experimental data. (C) 1999 Elsevier Science B.V. All rights reserved.
