摘要
采用半微量相平衡方法研究了三元体系Ｃｅ（ＮＯ３）３·３Ｈ２Ｏ－ １８Ｃ６－ Ｃ２Ｈ５ＯＨ 在３０３．１５Ｋ 时的溶解度，测定了各饱和溶液的折光率。该体系在３０３．１５Ｋ 时仅生成一种化学计量的配合物Ｃｅ（ＮＯ３）３·１８Ｃ６·３Ｈ２Ｏ。同时试验考察了相平衡过程中水的行为，合成分离了固态配合物，用化学分析，ＩＲ、ＤＴＧ、ＴＧ 及电导测定研究了配合物的组成和性质。
In the paper, the solubilities of the ternary system Ce(NO 3) 3·3H 2O-18C6—C 2H 5OH,at 303.15K have been investigated by the semimicro method for the study of phase equilibrium. The refractive indices for satuated solutions at 303.15k have been determined. The results indicated that there is only one stoichiometric comples Ce(NO 3) 3·18C6·3H 2O formed in the ternary system. The behavior of Water for this system in equilibrium has been examined.The solid coordination compounds have been prepared. The composition and properties of the complex have been investigated by chemical analysis,IR,TG.DTG and molar conductance.
