Liquid-Liquid Equilibria for Acetone + Several Citrates Aqueous Two-phase Systems at Different Temperatures
Liquid-liquid equilibria for the three kinds of the ternary systems acetone + ammonium,sodium or potassium citrate + water have been determined at T=(273.15,283.15,and 298.15) K.Binodal curves,tie-lines,and integrated phase diagrams for the ternary systems are given.The data of the experimental bimodal curve are described with a four-parameter equation.The result also shows the temperature has little influence on the liquid-liquid equilibrium within the investigated range.The tie-line data calculated according to the bimodal data fitting equation and the lever arm rule were satisfactorily described by using the Othmer-Tobias and Bancroft equations,and the result conform the reliability of the calculation method and corresponding tie-line data.
