Abstract

The NaClO₃⋅CO(NH₂)₂–CS(NH₂)₂–H₂O system has been studied using binary systems and eight internal cuts and a polythermal solubility diagram has been constructed in the temperature range from –34.2 to 48.2°C. The phase diagram of the polythermal solubility of the system has delimitated the crystallization fields of ice, CO(NH₂)₂, NaClO₃⋅CO(NH₂)₂, and CS(NH₂)₂. This system belongs to a simple eutonic type, the components have retained their individuality and have shown good solubility in water. In the [60%NaClO₃⋅CO(NH₂)₂ + 40%H₂O]–[CS(NH₂)₂] section, changes in crystallization temperature, viscosity, density, pH, and refraction indices of solutions in various component ratios have been studied and a “composition-properties” diagram has been constructed.

NaClO3·CO(NH2)2–CS(NH2)2–H2O 体系中组分的溶解度

摘要

NaClO ₃ ⋅CO(NH ₂ ) ₂ –CS(NH ₂ ) ₂ –H ₂ O 系统已使用二元系统和八个内部切割进行了研究，并在 –34.2 至 48.2° 的温度范围内构建了多热溶解度图C。_{系统的多热溶解度相图划定了冰、CO(NH 2} ) ₂、NaClO ₃ ⋅ CO(NH ₂ ) ₂和CS(NH ₂ ) ₂的结晶场. 该体系属于简单的共渗型，组分保留了各自的个性，在水中表现出良好的溶解性。在[60%NaClO ₃ ⋅CO(NH ₂ ) ₂ + 40%H ₂ O]–[CS(NH ₂ ) ₂ ]部分，不同溶液的结晶温度、粘度、密度、pH值和折射率的变化研究了成分比率并构建了“组成-特性”图。
