Liquid + liquid) equilibrium data of (tert amyl ethyl ether + ethanol + water) were determined experimentally at T = (298. 15, 308.15, and 318.15) K. The experimental results were correlated with the NRTL and UNIQUAC equations. The correlations were made at each temperature and for the three tempera

Total vapour pressure measurements made by a modified static method for the ternary mixture (N -methylacetamide + ethanol + water) and for the binary mixture (N -methylacetamide + ethanol) at the temperature 313.15 K are presented. Different expressions for the excess Gibbs free energy are tested, a
The heat capacities of the ternary system of 0.195 mole fraction of ethandiol (ethylene glycol), 0.132 mole fraction of ethanol (ethyl alcohol), and 0.673 mole fraction of water (i.e. 0.40, 0.20, and 0.40 mass fraction, respectively) have been measured with an adiabatic calorimeter in the temperatur
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
