The research team has obtained functionalized nitrogen-containing polysaccharides based on affordable low-molecular carboxymethyl cellulose. 90 thousands and ethanolamines. The paper shows that due to the specific reversible adsorption that occurs when seeds are nucleating, these polysaccharides alter the shape of the emerging crystal, inhibit the aggregation and agglomeration of CaCO 3 crystals, and reduce their size from 49.6 to 20.2 and 15.4 µm, respectively. Gravimetry shows that the corrosion rate of low-carbon steel 20 in a produced-water model is reduced when continuously running CO 2 in the presence of synthesized polysaccharides. The protective effect of the functionalized CMC derivatives is 15.8 to 18.6 percent stronger than for the original biopolymer. The obtained polysaccharide derivatives could be of use for developing corrosion and scaling inhibitors.
