研究四元体系CsCl-NdCl~3-13%HCl(42%HOAc)-H~2O(25℃)时的相平衡关系,绘制了相应的溶度图。两平衡体系中均有新相2:1型及1:1型化合物存在,为用Meyer方法合成相应的化合物提供了相化学依据。发现在所研究的体系中,盐酸溶液和醋酸溶液具有"等效介质效应"。

Solubilities of the staturated solution of quarternary systems of CsCl-NdCl~3-13%HCl-H~2O and CsCl-NdCl~3-42%HOAc-H~2O were studied at 25℃. The corresponding equilibrium diagrams were constructed. New compounds of 2:1 type and 1:1 type were discovered in the investigated systems. The discovery of new compounds gives out phase foundation for synthesizing the corresponding compounds using Meyer's method. In the investigated systems the "equal medium effect" for HCl and HOAc was found.

Key words: QUATERNARY SYSTEM, NEODYMIUM CHLORINE, CESIUM CHLORIDE, MEDIUM EFFECT, PHASE EQUILIBRIUM, COMPOUND CHARACTERIZATION
