Abstract:
By applying turbidity analysis, the equilibrium solubility of a ternary system of isopropyl alcohol and potassium hydrogen phosphate and water as well as the data of liquid liquid equilibrium of that system are determined at 35 ℃ and atmospheric pressure. Corresponding solubility diagram and phase diagram are drawn, and empirical equation of solubility ( R ≥0.999) is regressed. Moreover, the condition under which this aqueous two phase system are formed and the tentative law of phase equilibrium are investigated. As shown by experimental results, the phase formation of a stable aqueous two phase system depends upon the mass fraction of isopropyl alcohol ranging 0~1.00, potassium hydrogen phosphate ranging 0~0.728 6, and water ranging 0~0.681 4. This aqueous two system can be used for extraction and separation and purification of substance.
