CHAMBER INHIBITOR OF CORROSION OF FERROUS AND NON-FERROUS METALS Russian patent published in 2021 - IPC C23F11/02 

FIELD: metals corrosion protection.

SUBSTANCE: invention relates to the protection of metals from corrosion, namely to chamber atmospheric corrosion inhibitors. The corrosion inhibitor consists of a mixture of a nitrogen-containing base, which is used as triethanolamine, or dimethylethanolamine, or diethylethanolamine, or monoethanolamine, or octadecylamine, or hexamethylenetetramine, and a heterocyclic nitrogen-containing compound, which is used as chlorobenzene, or benzothriazole benzotriazole, or tolyltriazole, with the following ratio of components, wt.%: nitrogen-containing base 20-80; heterocyclic nitrogen-containing compound 20-80.

EFFECT: increasing the efficiency of protection of ferrous and non-ferrous metals from corrosion in atmospheres with a high chloride content.
