摘要
用半微量相平衡法研究了三元体系LaCl3-Ser-H2O在25℃时及全浓度范围内的溶度性质。结果表明:体系有两种化合物存在:La(Ser)Cl3·3H2O与La(Ser)2Cl3·5H2O。在相平衡结果指导下,制得了这两种固态配合物,用化学分析、摩尔电导、光谱、X射线衍射及热分析测定了它们的一些物理化学性质。
The solubility properties of LaCl 3 Ser H 2O system at 25℃ in the whole cocentration range have been investigated by semimicro phase equilibrium method. The result indicates that there are 2 complexes formed in the system: La(Ser)Cl 3·3H 2O and La(Ser) 2Cl 3·5H 2O. Under the direction of phase equilibrium result, 2 solid complexes have been prepared and characterized by chemical analysis, molar conductivity, spectra, X ray diffraction and thermogravimetric analysis.
