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

Abstract

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.
