【摘要】 测定了三元体系MCl-SbCl₃-HOAc（M=Li,Na;25℃）的溶度数据和饱和溶液的折光指数,并绘制了相应的溶度图及其折光指数曲线M=Li时,体系的溶度曲线和折光指数曲线均由三支组成,分别与LiCl·0.5HOAc,LiCl,SbCl₃相对应,M=Na时,体系属于简单共饱型,无任何新相形成.研究结果表明,当M分别是Li,Na或K,NH₄,Rb,Cs时,体系的物理化学行为有着极为显著的不同,说明MCl-SbCl₃-HOAc（M=Li,Na,K,NH₄,Rb,Cs）体系可以作为区分碱金属系列阳离子性质差别的典型体系.更多还原

【Abstract】 The solubilities and refractive indexes of saturated solutions of title systems (at 25℃ ) have been investigated and the corresponding equlibrium diagrams was constructed. When M = Li, there are 3 solid phases in the system: LiCl · 0.5HOAc, LiCl, SbCl3. While M = Na, the system belongs to simple eutectic type and any new phases were not discovered. This work and systems on M = K, NH4, Rb, Cs presents a profitable typical system for distinguish of different behaviour between alkali metal cations M+.更多还原
