A fatty acid mixture (FCA) was obtained from Technical Vegetable Oil − a Residue of Sunflower Oil production. Mass-spectrometry chromatogram analysis revealed that the mixture consists primarily of nine types of fatty acid. A new cationic surfactant (FCA-3-DMAPA surfactant) was obtained using the amidation reaction of a mixture of FCA with 3-dimethylamine-1-propylamine (3-DMAPA). The chemical structure of the synthesized surfactant was confirmed using mass-spectra chromatogram analysis, infrared, ¹H and ¹³C nuclear magnetic resonance spectra. The surface-active and colloid-chemical properties of the synthesized surfactant (critical micelle concentration (CMC), wetting of teflon surface, emulsifiering, flocculating and biocidal properties) were studied. The maximal Gibbs adsorption at water/air interface (Гmax=4.8×10-6 mol/m2), area occupied by one molecule of the cationic surfactant in the saturated adsorption layer (Аmin=0.35 nm2), surface-activity (ПСМС=39.8 mN/m) and zeta-potential (ζСМС=+71 mV) at CMC were determined. It was established that the obtained cationic surfactant has good wetting, emulsifying, flocculating and biocidal properties.
