Abstract: The relationship between the physicochemical properties of compounds and their inhibition factors g of the atmospheric corrosion of steel are discussed with Schiff and Mannich bases as examples. It is shown that the inhibitive efficiency of compounds can be predicted from correlations between g and calculated parameters such as saturated vapor pressure, total electron density on heteroatoms, and hydrophobicity constant. The predicted and experimental inhibition factors of new inhibitors agree to within ±10%.

Keywords: efficiency prediction, correlation analysis, atmospheric corrosion, steel, volatile inhibitors, Schiff and Mannich bases
