Synthesis, Surface Active and Thermodynamic Parameters of Novel Quaternary Ammonium Salts

Reactions of octanol, nonanol, decanol, and dodecanol with epichlorohydrin were carried out in the presence of sodium hydroxide as a catalyst. The synthesized non‐ionic surfactants were modified with triethanolamine. Surface activity at the water‐air interface and electrical conductivity of the resulting surfactants at 10, 20, 30 and 40 °C were determined and thermodynamic parameters of micellization and adsorption were calculated. It was established that the synthesized quaternary ammonium salts have the ability to localize thin crude oil films on the water surface formed due to spill.
