测定了NH4Cl＿NH4SCN＿H2O三元体系在0℃和30℃时的溶解度和饱和溶液的折光率,绘制了相应的溶度图及折光率图,结果表明0℃和30℃时体系的等温溶度图均为简单共饱型,其溶度曲线和折光率曲线均由两支构成,在0℃和30℃时共饱点的组成NH4Cl和NH4SCN的质量分数分别为5 82%,51 39%;6 70%,61 88%.
The solubility of NH4Cl_NH4SCN_H2O ternary system at 0 ℃ and 30 ℃ and the refractive index of saturated solution were measured. The corresponding solubility diagrams and refractive index diagrams were drawn. The results showed that the isothermal solubility diagrams of the system at 0 ℃ and 30 ℃ were Simple saturated, the solubility curve and refractive index curve are composed of two, at 0 ℃ and 30 ℃ co-saturation point composition of NH4Cl and NH4SCN mass fraction of 5 82%, 51 39%; 6 70% , 61 88%.
