FIELD: chemistry.
SUBSTANCE: inhibitor has an active part based on carboxylic acids, methanol, non-ionic surfactant, as well as an alcohol fraction from production of caprolactam and POD oil. The active part is obtained through synthesis of high-molecular and medium-molecular carboxylic acids with triethylene tetraamine, and the non-ionic surfactant is a mixture of neonols, with the following ratio of ingredients, wt %: active part 10.0-30.0, alcohol fraction from production of caprolactam 10.0-40.0, methanol 10.0-40.0, mixture of neonols 1.0-4.0, POD oil - the rest.
EFFECT: invention widens the range of efficient easily producible and cheap anti-corrosion agents for ferrous metals in oil and gas extraction and transportation systems.
