The solubilities of Cs 2 SO 4 -C 2 H 5 OH-H 2 O ternary system at 30℃and 50℃have been studied using microe-quipment for solubility determination.There appears two phases,alcoh olic phase,water phase in the liquid phase.The solubilities of Cs 2 SO 4 in water,C 2 H 5 OH and mixed solvent have been determ ined.The phase diagram indicated that C 2 H 5 OH might be salted out by Cs 2 SO 4 from this system and the equilibrium solid phase is Cs 2 SO 4 .
The solubilities of Cs 2 SO 4 -C 2 H 5 OH-H 2 O ternary system at 30 ° C and 50 ° C have been studied using microequipment for the determination of solvents. There are two phases, alcoh olic phase, water phase in the liquid phase. The solubilities of Cs 2 SO 4 in water, C 2 H 5 OH and mixed solvents have been determined. The phase diagram shows that C 2 H 5 OH might be salted out by Cs 2 SO 4 from this system and the equilibrium solid phase is Cs 2 SO 4.
