摘　　要：用半微量相平衡法研究了ＲＥＣｌ３－Ｓｅｒ－Ｈ２Ｏ（ＲＥ＝Ｎｄ，Ｇｄ，Ｙｂ）在２５℃及全浓度范围内的溶度性质。结果表明在这些体系中有６种三元配合物形成：ＲＥ（Ｓｅｒ）Ｃｌ３·３Ｈ２Ｏ与ＲＥ（Ｓｅｒ）２Ｃｌ３·５Ｈ２Ｏ（ＲＥ＝Ｎｄ，Ｇｄ，Ｙｂ）。在相平衡结果指导下，制得了２０种固态配合物，用化学分析确定了配合物的组成。The solubility properties of RECl3-Ser-H2O system(RE=Nd,Gd,Yb) at 25℃ in the whole cocentration range have been systematically investigated by semimicro phase equilibrium method. The results indicated that there are 6 ternary complexes formed in these systems:RE(Ser)Cl3· 3H,O and RE (Ser)2Cl3·5H2O (RE = Nd, Gd, Yb). Under the direction of phase equilibrium results, 20 solid complexes have been prepared, chemical analysis proved that the compositions of complexes are RE (Ser)Cl3· 3H2O and RE(Ser),Cl2, 5H2O,respectively.
