The liquid-liquid equilibria of the three ternary systems: water + 2-butanone + aliphatic alcohols (ethanol, 2-proponal, and 1-proponal) were each measured at 288.15, 298.15 and 308.15 K. Experimental data were correlated as a linear function of temperature using the UNIQUAC equation with the dimensionless parameters, tau(V). The root-mean-square-deviations between the correlated and experimental mole fractions were evaluated as 1.37, 0.87 and 1.16% for water + 2-butanone + ethanol, water + 2-butanone + 2-propanol and water + 2-butanone + 1-propanol, respectively.
