Abstract: Studies on the effect of inhibitor formulations based on IFKhAN-92 on the electrode reactions of mild steel in hydrochloric and sulfuric acid solutions have shown that these formulations considerably hinder the cathodic and anodic reactions on the metal at temperatures at least up to 100°C. This result allowed us to assume that it is possible to slow down steel corrosion efficiently by formulations based on IFKhAN-92 not only below 100°C but also at higher temperatures, as confirmed by corrosion tests in hydrochloric acid (up to 160°C) and sulfuric acid (up to 200°C).
