摘要： 关于钾盐-有机物-水体系的研究至今报导甚少,B·Begaliev[1]等对体系LiCl·CO(NH2)2-H2O进行了研究,发现有两个复合物:LiCl·CO(NH2)2,LiCl·3CO(NH3)2生成.为了进一步探讨这类体系中锂盐与有机物的相互作用,本文对LiCl·CS(NH2)2-H2O(Ⅰ)(0°,25℃)和LiCl-CH3CONHCONH2-H2O(Ⅱ)(0°,35℃)两个体系进行了研究.

Abstract: The solubilities and refractive indices of saturated solution of the systems LiCl-CS(NH2)2-H2O (Ⅰ) at 0℃, 25℃ and LiCl-CH3-CONHCONH2-H3O (Ⅱ) at 0℃, 35℃ are reported.The system (Ⅰ) is a simple eutonic one, its solubility curve and refractive index curve consist of two branches, corresponding to solid phases CS(NH2)2, LiCl·2H2O (0℃) or LiCl·H2O (25℃) respectively.In system (Ⅱ) an incongruently soluble compound LiCl·CH5CONH-CONH2 is formed.The solubility curve and refractive index curve of the system consist of three branches, corresponding to CH3CONHCONH3, LiCl·CH3CONHCONH2, and LiCl·2H2O (0℃) or LiCLH2O (35℃) respectively.LiCl·CH3CONHCONH2 shown for in this paper the first time,can be decomposed by the moisture of air.
