STUDY OF THE POLYTHERMIC SOLUBILITY OF THE H5CN3O4 · HOCH2CH2NH2 - [10 % C10H11ClN4 + 90 % C2H5OH] - H2O SYSTEM

Abstract

In this work, the interaction of the components in the H₅CN₃O₄ · HOCH₂CH₂NH₂ - [10 % C₁₀H₁₁ClN₄+ 90 % C₂H₅OH] - H₂O system was studied by visual polythermal method in the temperature range from -42°C to 13°C. A polythermal solubility diagram of the system was constructed and the crystallization areas of ice, acetamipride, urea, and ureanitrate monoethanolammonium were separated in the diagram. The binary and ternary points of the separated phase lines on the solubility diagram, projections were drawn and examined. The [10 % C₁₀H₁₁ClN₄+ 90 % C₂H₅OH] solution was selected considering the poor solubility of pure Acetamiprid in water. The [10 % C₁₀H₁₁ClN₄+ 90 % C₂H₅OH] - H₂O binary system was studied and the formed phases were analyzed using NMR spectroscopy (H 1 spectrum, C13 spectrum). In addition, ureanitrate monoethanolammonium compound was synthesized and analysed using physical chemical analysis methods (IR, Thermal).Dermatographic studies of the ureanitrate monoethanolammonium sample were studied in the mass size Δm_o= 45 mg, at a temperature change rate of 10°C min^-1, in the range from room temperature to ΔT = 800°C. The TG curves of the sample were determined by the results obtained from the dervatographic study.
