METHOD OF PROTECTION OF STEEL FROM CORROSION AND HYDROGENATION BY ORGANIC COMPOUNDS IN MEDIUM CONTAINING SULPHATE REDUCING BACTERIA Russian patent published in 2017 - IPC C23F11/14 

FIELD: chemistry.

SUBSTANCE: invention relates to the protection of metals from corrosion, hydrogenation and the development of sulfate-reducing bacteria (CRB) and can be used in aqueous-salt media containing CRB. The method includes the introduction of a bactericide inhibitor into the corrosive medium, the organic compound, a coordinatively saturated cobalt complex with two perpendicularly located tridentate ligands, the Schiff base of 5-Br-salicylaldehyde and the (S)-amino acid: asparagine, is used as the bactericide inhibitor, glycine, glutamine or leucine in an amount of 1, 2, 5, 10 mmol/l of the general formula , where R is the variable portion of the (S)-amino acid.

EFFECT: increasing the corrosion resistance of steel and expansion of assortment of inhibitors-bactericides.
