FIELD: metallurgy.
SUBSTANCE: invention relates to area of metal protection against corrosion in mineralised of trolly medium, including hydrogen sulphide, inhibitors and can be used with protection against corrosion pipelines and equipment in petrolic branch. Method includes addition into mineralised trolly medium corrosion inhibitor, at that in the capacity of corrosion inhibitor it is used N-acetyl-2-(2.3-dihydroxycilopentenyl) aniline with concentration 50-200 mg/l. Level of protection of steel is 87.8-96.0%.
EFFECT: increasing of steel protection rating.
