Solubility and Rheological Properties of the System NaClO3⋅CO(NH2)2–H2SO4⋅N(C2H4OH)3–H2O

This work is devoted to the study of the interaction of components in the system NaClO3⋅ CO(NH2)2–H2SO4⋅N(C2H4OH)3–H2O by visual-polythermal method. The solubility of the system has been studied in the temperature range from –33.0 to 70.0°C. Its polythermal solubility diagram has been constructed on which the crystallization fields of ice, carbamide, sodium monocarbamidochlorate, triethanolammonium sulfate, and a new compound of the composition triethylchlororatamine sodium sulfate are distinguished. The compound has been identified by chemical and physicochemical analyses. New data of physicochemical and rheological properties of the components of the system have been obtained (crystallization temperature, pH, density, viscosity, and refractive index), and a “composition-properties” diagram of the studied system has been constructed.
