STUDY OF THE POLYTHERMAL SOLUBILITY AND RHEOLOGICAL PROPERTIES OF THE SULFOSALICYLIC ACID DIHYDRATE - MONOETHANOLAMINE - WATER SYSTEM

In this work, the polythermal solubility of the three-component system containing C7H6 O6S∙2H2 O - NH2C2H4OH - H2O was studied in the visual polythermic method based on binary systems and internal sections in the temperature range from -50.2°C to 42.0°C, and the diagram was constructed. In the solubility diagram, based on the phase-separating binary and ternary points the table was created, and the projection was drawn. In the diagram, the crystallization areas of ice, C7H6O6S, C7H6O6S∙2H2O, NH2C2H4OH∙2H2O, NH2C2H4OH∙H2O, NH2C2H4OH, and a new chemical compound C7H6O6S∙NH2C2H4OH were separated. A new phase formed during the study of the C7H6O6S∙2H2O - NH2C2H4OH - H2O system was separated, and the separated phase was analysed using chemical, physico-chemical methods and the presence of a new chemical compound (C7H6O6S ∙ NH2C2H4OH) was confirmed.
