STUDY OF SOLUBILITY PROPERTIES OF COMPONENTS IN ACETATE UREA - TRIETHANOLAMINE - WATER SYSTEM

Abstract

In this work, in order to synthesize new physiologically active substances, the solubility properties of the components in the acetate urea triethanolamine water ternary system were studied by observational polythermal method at a wide range of concentration and a temperature range from -43°C to 18°C. The solubility diagram of the studied system was constructed and the crystallization areas of all substances acetateurea, triethanolamine, ice and the new compound С3Н8O3N2∙N(C2H4OH)3 acetate ureatriethanolammonium were separated. The composition of the new substance С3Н8O3N2∙N(C2H4OH)3 was determined using the chemical analysis method. In order to determine optimal conditions for the synthesis of С3Н8O3N2∙N(C2H4OH)3 acetate ureatriethanolammonium, which has a new physiologically active property, the rheological properties of the solution were studied by adding triethanolamine to 60, 70 and 80 % acetateurea. A “composition-property” diagram was constructed based on the rheological properties of the studied system, the рH indicator, the density and viscosity of the solution, and the refractive index. The optimal conditions for the synthesis of the new substance С3Н8O3N2∙N(C2H4OH)3 acetate ureatriethanolammonium, obtained by the ratio of components, were determined by adding triethanolamine to a 60 % acetate urea solution.
