引言体系 LiI—Li_2SO_4—H_2O 的溶解度迄今尚未有人作过,为了找出 LiI 与 Li_2SO_4在水中溶解度的相互影响与化学行为,作者选作了该体系在0℃时溶解度的研究。体系 LiCl—I_4i_2SO_4—H_2O 在30°和25°的溶解度图均被研究过,结果证明 I_4i_2SO_4在水中的溶解度随溶液中 LiCl 含量的增加而迅速的减低。体系的溶解度曲线由两支构成,分别相应于 Li_2SO_4·H_2O 与 LiCl·H_2O,但与 LiCl·H_2O 对应的一支极短,只留下与 Li_2SO_4·H_2O对应的一支。在25℃时共晶点含 Li_2SO_40.02%;含 LiCl45.52%。体系 NaI—Na_2SO_4
Introduction The solubility of LiI-Li_2SO_4-H_2O has not been studied yet. In order to find out the interaction and chemical behavior of LiI and Li_2SO_4 in water, the authors chose the solubility of LiI-Li_2SO_4-H_2O at 0 ℃. The solubility diagrams of LiCl-I_4i_2SO_4-H_2O at 30 ° and 25 ° have been studied. The results show that the solubility of I_4i_2SO_4 in water decreases rapidly with the increase of LiCl content in solution. The solubility curve of the system is composed of two branches, corresponding to Li_2SO_4 · H_2O and LiCl · H_2O, respectively. However, one branch corresponding to LiCl · H_2O is short and only one branch corresponding to Li_2SO_4 · H_2O remains. At 25 ℃, the eutectic point contains Li_2SO_40.02% and LiCl contains 45.52%.
