VOLATILE CORROSION INHIBITOR Russian patent published in 2006 - IPC C23F11/02 

FIELD: corrosion inhibitors.

SUBSTANCE: invention proposes a corrosion inhibitor comprising the following components, wt.-%: alkylimidazolines, 0.5-4; para-nitrophenol, 3.0-3.1; triethylamine, 0.5-5, and isopropyl alcohol, the balance. Invention provides increasing longevity of constructions based on enhancing protective properties of inhibitor and enhancing stability of a protective film formed on metal at adsorption of inhibitor vapor by metal surface. Invention can be used in protection of machine and mechanism members working in contact with corrosive agents in machine engineering, and for protection of petroleum-extracting equipment, containers, reservoirs and cisterns against corrosion.

EFFECT: improved and valuable properties of inhibitor.
