Protective Ability

This work is a continuation in a series of studies on the preparation of acid corrosion inhibitors based on carboxylic acids. A method of synthesis of acid corrosion inhibitors based on oleic acid amides has been developed. Several syntheses have been carried out to increase its inhibitory properties. The substances were obtained in several stages. At the first stage, amino alcohols were added to the ОA, then the resulting compounds were sulfonated with sulfuric acid. To expand the field of various inhibitors, reactions with bases are produced. As a result, salts of sulfated amides of oleic acid synthesized with amino nitrates, sulfuric acid and aqueous solutions of bases were formed. To establish the effectiveness of the compounds obtained, the protective ability in dilute hydrochloric acid was evaluated. It is established that some of the obtained substances exhibit the corresponding properties of inhibitors. In this case, the most effective is the ammonium salt of sulfated diethanolamide oleic acid.

Predicted Values

Diffusion of sulfuric acid in aqueous solution has been measured by a conductimetric technique at 25 °C over the concentration range from 0.00035 to 0.2 mol dm−3. At the lower end of this range, dissociation of bisulfate to sulfate and hydrogen ions produces a sharp increase in the rate of diffusion of the sulfuric acid component. Expressions are developed to predict the concentration dependence of the diffusion coefficient in terms of the mobilities of the diffusing ions and the degree of bisulfate dissociation. The treatment includes electrophoretic corrections that are derived from Onsager–Fuoss theory for the unsymmetrical, multi-ion electrolyte. At low concentrations where theory applies the observed diffusion coefficients are lower than the predicted values.
