Abstract
The effect of alkylphenol sulfuric acid on the corrosion process of St10 steel in the two-phase 0,1 N HCl solution – kerosene system of magnesium, zinc and barium salts, (conventionally indicated as Mg-HГПИ-2, Zn-HГПИ-2 and Ba-HГПИ-2) previously studied on St3 steel samples, was confirmed by gravimetric method. It was determined that, all of the compounds shown in the 25...200 mg/L concentration range significantly weakens the corrosion process of St10 steel in the mentioned two-phase acid system. It is shown that, their effectiveness in analogous conditions does not differ sharply from each other and this is also associated with the fact that the structures of the ions Mg2+, Zn2+, Ba2+ do not differ sharply from each other, as well as with being the same of organic anion, which has a decisive role in the ads orption process. It is also shown, that corrosion characteristics of St10 steel in the shown system are very clos e to each other
