摘要： 采用自制微型平衡溶解度测定装置,测定了CsCl-C2H5OH-H2O三元体系全温度范围内的平衡溶解度,绘制成相应的相图.首次报道氯化铯在乙醇水混合溶剂中于30,40和50℃时的分层现象,通过实验得到氯化铯在乙醇水混合溶剂中的分层温度.用Schreinemarkers"湿渣结线法"确定实验温度范围的平衡固相为无水CsCl.

Abstract: The isothermal solubility of CsCl-C2H5OH-H2Oternary system in the range of whole temperature was determined and the phase diagram was constructed. The CsCl C2H5OH H2Oternary system at 30, 40 and 50℃ appeared in two liquid phases, alcoholic phase and water phase, while there was only one phase in the CsCl C2H5OH H2Oternary system at 20 ℃. By means of the experiment the critical temperature that appeared in two liquid phases was gained. The equilibrium solid phase is CsCl.

Key words: Cesium chloride, Ethanol, Ternary system, Phase equilibrium, Solubility
