SYNTHESIS OF NEW STARCH DERIVATIVES CONTAINING 2-AMINOETHYL HYDROGEN SULFATE

The article is devoted to the synthesis of new starch derivatives containing 2-aminoethyl sulfate. The study examined the influence of various parameters on the process of modification of polysaccharides, including reaction time, pH of the medium, temperature and concentration of reagents. Optimal reaction conditions were determined. The structure of the resulting product was analyzed using spectroscopy methods, including infrared spectroscopy. Additionally, the nitrogen content in the macromolecule was determined in order to assess the degree of modification, since nitrogen is often introduced into the molecule through amino groups, changing its properties and functionality. The influence of the amount of nitrogen on the formation of azomethine bonds and their distribution in the macromolecule was studied. It has been established that an increase in the number of sulfate groups in a macromolecule leads to an increase in its acidity, which can be an important factor when considering its biological activity. The results obtained represent an important contribution to the understanding of polysaccharide modification processes and their application in various fields of science and industry.
