Abstract

Abstract: In this paper, the solubility of ternary system Li₂SO₄-C₂H₅OH-H₂O has been determined at -20℃, 0℃, 30℃ and 50℃ respectively; It has been found that the equilibrium solid phase in the range of studied concentration and temperature is Li₂SO₄·H₂O, which decreases its solubility in water with increase of temperature, but dissolves a little in ethanol. The isothermal solubility data have been correlated by experimental formulae.

Key words: Phase equilibrium, Solublity, Ternary system, Lithium sulfate, Ethanol
