Abstract: Solubility of Cs2CO3-C2H5OH H2O ternary system at 30 ℃ has been studied by using micro equipment for solubility determination. There appear two phases, alcoholic phase and water phase, in the liquid phase. The solubility of Cs2CO3 in water, C2H5OH and mixed solvent has been determined. The phase diagram indicated that C2H5OH might be strongly salted out by Cs2CO3 from this system and the equilibrium solid phase is Cs2CO3·3.5H2O.

Key words: Cs2CO3, Ethanol, Ternary system, Solubility, Cs2CO3·3.5H2O
