摘要： 研究含锂和其他碱金属及碱土金属盐类多组分水盐体系的相图,特别是将HCl引入水盐体系,进行锂镁氯化物盐析萃取分离的研究,对于从青藏高原盐卤中分离提取锂盐有重要的意义。BockpeceHckая等[1]测定过LiCl-MgCl2-H2O的等温溶解度,Dähne等[2]测定过HCl-MgCl2-H2的等温溶解度。

关键词: 氯化氢, 氯化锂, 氯化镁, 相平衡, 等温溶解度

Abstract: The isothermal solubilities of ternary systems HCl-MgCl2-H2O and LiCl-MgCl2-H2O at -10℃ have been determined. Three crystallization fields corresponding to MgCl2·8H2O, MgCl2·6H2O and HCl·MgCl2·7H2O and three crystallization fields corresponding to MgCl2·8H2O,MgCl2·6H2O and LiCl·2H2O have been found for the first and second systems respectively.The existence of LiCl·MgCl2·7H2O and so called"2nd double salt"reported in[1]hasn't been found in this work.The salt-out rates of HCl and LiCl to MgCl2 were compared.

Key words: hydrogen chloride, lithium chloride, magnesium chloride, phase equillibrium, isothermal solubility
