Imidazoline derivatives have been synthesized on the basis of synthetic petroleum acids and triethylentetramine. Complexes were prepared from the above-stated compounds and HCl in the ratio 1:2, 1:3. Note that 20% solutions of the complexes were prepared in aqueous isopropyl alcohol. The kinetic effect of steel corrosion in CO2 -saturated 1% NaCl solution has been examined by ACM Gill AC potentiometer. It revealed that imidazoline derivative complexes based on the SPA and TETA with HCl in the molar ratio 1:2 at concentration of 25 mg/l had corrosion protection 87.0%, at concentration of 50 mg/l 96.4% and at concentration 100 mg/l 97.1%; however, in the mole ratio of 1:3 the complex reveals its best results – 93.8, 97.8 and 98.4%.
