Synthesis of a Novel Surface-Active Agent Based on Hexadecylamine and Ethylene Chlorohydrin for the Removal of Thin Oil Films from Water Surfaces

A novel surface-active salt based on hexadecylamine and ethylene chlorohydrin was successfully synthesized. The composition and molecular structure of the synthesized salt were characterized by Fourier-transform infrared (FTIR) and UV–Visible (UV–Vis) spectroscopy, while its principal physicochemical properties were determined. Tensiometric measurements demonstrated the high surface activity of the synthesized salt at the air–water interface. The specific electrical conductivity of its aqueous solutions was measured using an electroconductometric method, confirming that the synthesized salt exhibits electrolyte behavior. The aggregate sizes of hexadecylethanolammonium chloride (HDEAC) in aqueous solutions at different concentrations were determined by dynamic light scattering (DLS), and the corresponding particle size distribution histograms were obtained.
