Popis: Functionalized nitrogen-containing polysaccharides based on available low molecular weight sample of carboxymethylcellulose (CMC) with a molecular mass of 90 thousand and mono-, di- and tri- ethanolamine were obtained. The study of CMC salts with ethanolamine as inhibitors of salt deposition was carried out at 80 °C by capillary testing. It was shown that at the concentration of 10-30 mg/l these salts inhibit the processes of scale deposition of CaCO3 and their efficiency is 53-80%. Rheological and sedimentation characteristics of artificially obtained water-oil (w/o) emulsions based on oil of the Priobskoye oilfield without and in the presence of low molecular weight sodium salt of carboxymethylcellulose (NaCMC) were studied. It was found that the NaCMC does not increase the viscosity and stability of W/O emulsions at concentrations of 50, 100, 200 mg/l.
