An aminoamide containing a hydroxyl group was synthesized from the reaction of a soybean oil acid mixture with hydroxyethylethylenediamine. The obtained aminoamide was then oxypropylated with propylene oxide. The composition and structure of the synthesized aminoamide and its oxypropyl derivatives were determined by FTIR spectroscopy. The synthesized products were characterized by their important physico-chemical properties, and conductometric measurements of their aqueous solutions at different concentrations were carried out. The colloid-chemical parameters of the synthesized surfactants were studied, and their adsorption properties were determined experimentally. Simultaneously, the critical micelle concentration, surface pressure, maximum adsorption, minimum surface area of the molecule, adsorption efficiency, and free Gibbs energy of micellization and adsorption were calculated. The petro-collecting and petro-dispersing properties of the obtained products were studied in a thin oil layer on the surface of different types of water.
