FIELD: chemistry.
SUBSTANCE: invention relates to protection of metals against corrosion and can be used to protect equipment in the oil industry. Method comprises adding to the mineralized aqueous phase a water-oil emulsion of N-heptyl-1,4-phenylenediamine in a concentration of 50–200 mg/l.
EFFECT: increase the degree of steel protection from corrosion, reduce the corrosion rate of steel.
