The influence of salts of substituted benzoic acids on steel behavior in chloride-containing solutions Ca(OH)_2 was studied. It was shown that the studied compounds inhibit local metal depassivation, elevating its potential and extending its induction period. The efficiency of inhibiting protection decreases when both hydrophilic and hydrophobic substituents are introduced in the aromatic nucleus of benzoic acid. The possible mechanism of the influence of substituent nature on protective properties of the studied compounds was considered.
