STUDY OF THE OIL DETERGENT AND OIL DISPERSING PROPERTIES OF QUATERNARY AMMONIUM SALTS TREATED WITH HEPTANE ACID WITH TRIETHANOLAMINE
Abstract
At present, the wide application of surfactants in various fields such as detergents, foam and emulsion stabilizers, fluorogens, hydrophobizers, corrosion inhibitors makes their synthesis considered 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 heptanoic 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 heptanoic 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.
In the quaternary ammonium salt of heptanoic acid with TEA, the mass fraction of carbon is 55.9%, the mass fraction of hydrogen is 10.5%, the mass fraction of oxygen is 28.6%, and the mass fraction of nitrogen is 5%.
The complex of heptanoic acid and TEA exhibits the ability to accumulate oil in seawater, both in the pure and 5% percent form of the reagent.
Solutions of various concentrations of the complex formed by heptanoic acid with triethanolamine are well soluble in ethyl and isopropyl alcohols.
