Abstract

In this work, the interaction of components in the CO(NH2)2 - HOOC - COOH ·NH2C2H4OH - H2O system was studied by visual polythermic method in the temperature range from -11.2 to 61°C. A polythermal solubility diagram of the system was constructed and the crystallization sites of ice, urea, monoethanolammonium oxalate, and the new phase ureamonoethanolammonium oxalate were determined.During the addition of monoethanolammonium oxalate to urea solutions of different concentrations, changes in rheological properties (pH, density, refractive index, viscosity) were recorded, and the results were found to be consistent with the polythermal solubility diagram. A new phase formed during the study of the CO(NH2)2 - HOOC-COOH · NH2C2H4OH - H2O system, ureamonoethanolammonium oxalate, was isolated and analyzed by confirmed using appropriate analytical methods (IR, Thermal, X-ray phase).
co(nh2)2 - hooc - cooh - nh2c2h4oh - h2o 系统的溶解度研究
本研究采用目视多热法研究了 CO(NH2)2 - HOOC - COOH -NH2C2H4OH - H2O 体系中各组分在 -11.2 至 61°C 温度范围内的相互作用。在不同浓度的尿素溶液中加入草酸单乙醇铵的过程中,记录了流变特性(pH 值、密度、折射率、粘度)的变化,结果与多热溶解度图一致。在研究 CO(NH2)2 - HOOC-COOH - NH2C2H4OH - H2O 体系过程中形成的一种新相--草酸尿氨乙醇铵被分离出来,并通过使用适当的分析方法(红外、热、X 射线相)进行分析确认。
