Utilisation de l'equation de hansch pour l'etablissement de correlations proprietes structures dans le domaine de l'inhibition de corrosion. Role de l'hydrophobie et de la polarite

Abstract

In deaerated media containing hydrogen sulfide, the inhibition of the corrosion of steel by homologous series of aliphatic amines and imidazolines was measured potentiokinetically. The data obtained were correlated successfully to the hydrophobicity and the polarity (calculated parameter) of these molecules by means of Hansch relationship.
