Cu(NO3)2(La(NO3)3)-CO(NH2)2-H2O三元体系的等温溶度研究
STUDY ON THE ISOTHERMAL SOLUBILITY OF THE TERNARY SYSTEMS Cu(NO3)2(La(NO3)3)-CO(NH2)2-H2O
【摘要】 本文首次报道三元体系Cu(NO3)2-CO(NH2)2-H2O(30℃)和La(NO3)3-CO(NH2)2-H2O(25℃)的等温溶度及饱和溶液、折光率,绘制相应的溶度图及折光率-组成图。体系中发现有组成为Cu(NO3)2·4CO(NH2)2、La(NO3)3·2CO(NH2)2·3H2O、La(NO3)3·4CO(NH2)2·H2O和La(NO3)3·6CO(NH2)2 的4 个新化合物相,且均为同成分溶解的化合物。通过元素分析、红外光谱分析、X-射线粉末衍射、热分析(仅对含结晶水的化合物)对其进行了表征
【Abstract】 The isothermal solubilities of the ternary systems Cu(NO 3) 2 CO(NH 2) 2 H 2O (30℃) and La(NO 3) 3 CO(NH 2) 2 H 2O (25℃) have been studies. There are 4 new compounds Cu(NO 3) 2·4CO(NH 2) 2、 La(NO 3) 3·2CO(NH 2) 2·3H 2O、 La(NO 3) 3·4CO(NH 2) 2·H 2O and La(NO 3) 3·6CO(NH 2) 2 found in the systems, which are congruently to dissolve in water at room temperature. These compounds have been characterized by IR, X ray and TGA.$$$$
