FIELD: metallurgy, plating.
SUBSTANCE: invention concerns metals protection against corrosion field and can be used for corrosion inhibition in metal pipelines. Inhibitor has a formula 
where R1 is alkyl radical, containing from 2 till 8 carbon atoms, R2 is fatty acid residue, and R3 is unsaturated acid residue. Inhibitor corresponds acrylate N-propyl-2-heptadecenylimidazolineail acrylate N- butyl -2- heptadecenylimidazoline or acrylate N-hexyl-2-heptadecenylimidazoline. Inhibitor is added to liquid in metal pipeline for increasing of degree of corrosion prevention.
EFFECT: providing of effective corrosion prevention.
