The adsorption and protective properties of the corrosion inhibitors SolIng IK-2, IK-3, and IK-4(A) are studied by the method of electrochemical impedance spectroscopy. It is found that these inhibitors efficiently protect against corrosion in 1 M HCl solution. The calculated degrees of surface filling indicate a high adsorption capacity of the studied compounds, which strongly depends on their composition. SolIng IK-2 and IK-4(A) are the most effective compositions exhibiting a high degree of surface filling already at low concentrations (at concentrations up to 0.025 g/L θ = 0.6–0.98).
