摘要: 在继[1,2]的研究之后,我们又研究了Жолалиева,З.М. 等人报导得到的LaCl3·6H2O的另一体系LaCl3-CH3CONHCONH3-H2O[3],以探讨LaCl3·6H2O在盐水有机体系中生成的可能性,并考察体系是否会出现其它的化学行为。

Abstract: Both the isotherms of solubilities and refraction indices of the system consist of three branches corresponding to the solid phases: LaCl3·7H2O, LaCl3·2CH3 CONHCONH2·5H2O and CH3CONHCONH2. Two eutonics contain LaCl3 and CH3CONHCONH3 47.68%, 8.48% and 41.63%, 15.64%, respectively. The ternary compound is an incongru-ently soluble one. Its density determined as described in the previous work is adout 1.75(17℃). Its photomicrograph is also given in this paper.
