STUDY OF THE POLYTHERMIC SOLUBITY SYSTEMS OF UREA IN AQUEOUS SOLUTIONS WITH OXALATE ACID AND OXALATE MONOETHANOLAMMONIUM
Keywords:
Usually, agricultural plants are treated with various stimulators in order to accelerate the growth and development of the cropAbstract
In this work, polythermal solubility diagram of Urea in aqueous solution with oxalic acid and monoethanolammonium oxalate was constructed. The H2C2O4•2H2O - CO(NH2)2 - H2O system was studied in the temperature range from -11.2 to 92 °C using binary systems and internal cross-sections, while the CO(NH2)2 - HOOC-COOH • NH2C2H4OH - H2O polythermal solubility diagrams were constructed in the temperature range from 0 to 61 °C. Crystallization areas of ice, urea, dihydrate oxalic acid, oxalate urea, oxalate monoethanolammonium, and oxalateurea monoethanolammonium were separated in the diagrams. In both systems, the crystallization fields intersect at two ternary points.
