FIELD: anticorrosion agents.
SUBSTANCE: invention relates to technique for anticorrosion protection of carbon steel in aqueous media. The composition comprises oxyethylidene diphosphonic acid, organic amine compounds and glycol. Composition comprises alkyldimethylamine oxide as an amine organic compound and propylene glycol as glycol in the following ratio of components, wt.-%: oxyethylidene diphosphonic acid, 1-58; alkyldimethylamine oxide, 1-26; propylene glycol, 1-30, and water, the balance. Invention provides development of the composition with complex effect allowing carrying out the effective protection of equipment against saline deposits, carbon steel corrosion and all slag deposit in water-return systems. Invention can be used in different branches of industry for protection of heat-exchange and cooling equipment.
EFFECT: valuable properties of composition.
