Effect of some compounds on the sensitivity of the inhibitive properties of o-hydroxyazomethine derivatives to variation in the polarity of their electrophilic substituents

Abstract

The sensitivity of the protective effect of an inhibitor from a reaction series to the variation of the polarities of electrophilic substituents in its molecule depends on the nature and concentrations of salt additives. The correlations obtained for iron corrosion were interpreted in terms of the Linear Gibbs Energy Relation (LGER) and the Principle of Hard and Soft Acids and Bases (HSAB).
