Sm(ClO_4)_3-Ala-H_2O三元体系在35℃时的相平衡研究

A Study Phase Equilibrium of Ternarg System Sm(ClO_4)_3-Ala-H_2O at 35℃

测定了Sm（ClO4）3－Ala－H2O三元体系在35℃时的溶解度和饱和溶液折光率，构制了相应的溶解度图和饱和溶液折光率曲线。溶解度曲线与折光率曲线均由4支组成，分别与Sm（ClO4）3·8H2O，Sm（Ala）4（ClO4）·2H2O（A），Sm（Ala）3（ClO4）3·3H2O（B）和Ala的晶体相对应。

篢he solubilities and refractive indexes of saturated solutions of the ternary System of Sm(ClO4)3 -Ala-H2O at 35℃, the corresponding equilibrium solubility and regractive index diagram are studied,All the solu-bility and refractive index curves of the systems consist of four branches, corresponding to Ala, complexes Sm (Ala)4 (ClO4)3· 2H2O,Sm(Ala)3 (ClO4)3·3H2O and Sm (ClO4 )3·8H2O respectively.
