The activity coefficient data were reported for (water + potassium chloride + DL-valine) at T = 298.15 K and (water + sodium chloride + L-valine) at T = 308.15 K. The measurements were performed in an electrochemical cell using ion-selective electrodes. The maximum concentrations of the electrolytes
Liquid + liquid) equilibrium tie-lines were measured for the two quaternary systems = 101.3 kPa. The experimental (liquid + liquid) equilibrium results have been satisfactorily correlated by modified and extended UNIQUAC models both with ternary and quaternary parameters in addition to binary ones.
