The protective properties of six corrosion inhibitors based on imidazolines, amides, amines and esters have been determined using gravimetric and potentiometric methods. The effect of inhibitor solvent on the protective properties has been examined. The dependence of inhibitor protective effect upon the content of nitrogen and functional groups has been determined. The most effective inhibitors have been chosen and their IR-spectra have been shown.
