| Abstract: | The solubilities, refraction indices of saturactedsolutions of the systems NH_4I—LiI—H_2O(Ⅰ), LIi—LiBr—H_2O(Ⅱ) and NH_4Br—LiBr—H_2O(Ⅲ), as the boundary ternary systems of the quaternary reciprocal systems Li~+, NH_4~+//Br~-, I~-—H_2O. have been investigated by isothermal method at 298.2K. These three systems all belong to simple eutectictype ones. The composition data of the eutectic points are NH_4I 6.28. LiI 57.39(Ⅰ); LiI 23.71, LiBr 41.14 (Ⅱ); NH_4Br 3.52, LiBr 58.91 (Ⅲ)％mass, respectively. |
