Abstract

The Сa(ClO₃)₂∙NH₄Сl–H₂O system has been studied in its constituent binary systems and seven inner sections, and its polythermal solubility diagram has been plotted in the range of temperatures from–42.5 to 87.5°С. The solubility diagram features the crystallization fields of ice; calcium chlorate hexahydrate, tetrahydrate, and dihydrate; and ammonium chloride. Three ternary points exist in the system. The system belongs to the complex eutonic type; its components retain their individuality and show good solubility in water. In the [40% Сa(ClO₃)₂ + 60% H₂O]–[NH₄Сl] section of the studied system, variations in crystallization temperature, viscosity, density, pH, and refractive indices of the solution have been determined. The thus-obtained results have been used to plot the composition–property diagram of the [40% Сa(ClO₃)₂ + 60% H₂O]–[NH₄Сl] section of the Сa(ClO₃)₂∙NH₄Сl–H₂O system.

摘要

研究了Сa(ClO ₃ ) ₂ ∙NH ₄ Сl–H ₂ O系统的二元系统组成和七个内部部分，并在–42.5至87.5°С的温度范围内绘制了其多热溶解度图。溶解度图描绘了冰的结晶场；六水氯酸钙、四水氯酸钙和二水氯酸钙；和氯化铵。系统中存在三个三元点。该系统属于复杂优调型；其成分保留其个性并在水中表现出良好的溶解度。在研究系统的 [40% Сa(ClO ₃ ) ₂ + 60% H ₂ O]–[NH ₄ Сl] 部分中，测定了溶液的结晶温度、粘度、密度、pH 值和折射率的变化。由此获得的结果已用于绘制 Сa(ClO ₃ ) _{2 ∙} NH 的 [40% Сa(ClO 3 ) ₂ + 60% H ₂ O]–[NH 4 _Сl ] 部分的组成-性质图₄ Сl–H ₂ O系统。
