FIELD: metal industry.
SUBSTANCE: means for protecting metals from corrosion, namely to the use of 5-(2H-1,3-benzodioxol-5-ml)-N-(1,3-dithiolan-2-ylidene)-1,3,4-thiadiazole -2-amine of Formula 1 as a corrosion inhibitor for St3 steel in the concentration range of 50-200 mg/l in a 15% aqueous solution of HCl at a temperature of 20°C and when heated to 80°C. The invention can be used in the oil industry for acid treatment of drill wells, as well as for treatment of the bottom-hole zone of oil and water injection wells.
EFFECT: reducing the corrosion rate of St3 steel.
