Synthesis methods for new corrosion inhibitors for neutral and acid media have been developed based on benzoic acid and its derivatives (benzyl benzoate, biphenylcarboxylic acid, benzoic acid, distillation residue) and amino alcohols (monoethanolamine, diethanolamine). The conditions required for synthesis have been optimized. The action mechanism of the inhibitor in 5% hydrochloric acid has been studied by the method of polarization carves. Possible applications for the novel inhibitor have been determined.
