Abstract

To obtain the highly effective complex-acting defoliant, the Сa(ClO3)2∙2CO(NH2)2-C4H6O5∙NH2C2H4OH-H2O system was studied using binary systems and ten internal sections, and the visual polythermal solubility diagram was constructed in the range of -24.2°C to 32.0°C. In the diagram, the crystallization areas of ice, Сa(ClO3)2∙2CO(NH2)2∙2H2O and C4H6O5∙NH2C2H4OH were separated. This system belongs to the simple eutonic type, the components have preserved their individuality and showed good solubility in water. In the [55 % Сa(ClO3)2∙2CO(NH2)2 + 45 % H2O]-[C4H6O5∙NH2C2H4OH] system, when the components are added in different proportions, the pH, crystallization temperature, refractive index, viscosity, and density changes of the solution were determined, and a “composition-property” diagram was constructed.
