FIELD: metallurgy.
SUBSTANCE: invention relates to protection of metals against corrosion. Corrosion inhibitor comprises compound that has hydrophobic group including whatever alkyl group with long molecular chain and whatever cyclic alkyl group and chelate group in molecular structure. Said compound is obtained by reaction of condensation between one any alkyl compound with long molecular chain and cyclic alkyl compound, and chelate ligand wherein alkyl compound with long molecular chain represents any compound of series consisting of alkyl carboxylic acid, ether of alkyl carboxylic acid, alkyl carboxylic amide of alkyl carboxylic acid, alkyl alcohol, alkyl thiol, alkyl aldehyde, alkyl ether, alkyl amine with long molecular chains. Note here that cyclic alkyl compound represents whatever compound containing group of carboxylic acid, hydroxyl group, amide acid group and thiol group, and wherein chelate ligand represents one of ethers of 3-keto-carboxylic acid, polyphosphate, amino carboxylic acid, hydroxyl carboxylic acid, polyamine, amino alcohol, and hydroxyl hydroxyethyliden phosphonic acid.
EFFECT: proposed material is made by applying above described composition, higher protection efficiency.
