FIELD: chemistry.
SUBSTANCE: invention relates to steel corrosion inhibitors with oxygen depolarisation and scaling based on complexes of nitrilotrismethylene phosphonic acid with zinc and is particularly intended to protect steel parts of equipment in oil and gas, chemical, food and other industries. The corrosion and(or) scale inhibitor contains a nitrilotrismethylene phosphonate zincate ion of formula or a nitrilotrismethylene phosphonate zincate ion with a dimeric structure.
EFFECT: obtaining an effective inhibitor with high thermodynamic stability, a uniform molecular structure, permanent and reproducible properties, storage stability, does not cake, does not produce dust and is easily soluble in water.
