ABSTRACT
Liquid-liquid equilibrium data for the ternary systems (1-propanol, 2-propanol, 2-methyl-2-propanol, 1-butanol and 2-butanol + di-sodium hydrogen citrate + water) were measured at T = 298.15, 308.15 and318.15 K. The phase-separation ability of the studied systems was discussed on the basis of the solubilityof the constitutive alcohol. Furthermore, the effect of temperature on the tie-line at investigated systemswas discussed. The Merchuk equation with three parameters as the temperature dependency form wassuccessfully used for the correlation of binodal data in working temperatures. In addition, the experimental tie-line data were reproduced using the Setschenow-type equation, the generalized e-NRTL and generalized Wilson models.
