A comparative study of the quaternary ammonium salts of enanth and undecanoic acids treated with triethanolamine

Abstract

At present, the wide application of surfactants in various fields such as detergents, foam and emulsion stabilizers, fluorogens, hydrophobizers, and corrosion inhibitors makes their synthesis one of the urgent issues. In the article, the results of the study of oil-collecting and oil-dispersing properties of the quaternary ammonium salt formed by triethanolamine (TEA) of enanthic acid, which is a monobasic carbonic acid, in distilled, drinking, and seawater contaminated with Balakhani oil are given. The surface activity property of the products of different concentrations of this complex was calculated using a tensiometer, and the element content was calculated using the calculation method. The complex formed by enanthic acid with TEA shows high surface activity by reducing the surface tension from 71.98 mN/m to 26.3 mN/m at that boundary.

The complex of enanthic acid and TEA exhibits the ability to accumulate oil in seawater, both in the pure and 5% forms of the reagent.

The complex formed by undecanoic acid with TEA shows high surface activity by reducing the surface tension from 71.98 mN/m to 23 mN/m at that boundary.
