Abstract

New benzalkoniumchloride derivatives ionic liquids (ILs) were synthesized in ≥ 97% yield and their inhibiting properties for the corrosion of carbon steel in formation water had been evaluated using chemical methods. The structures of the ILs compounds were investigated by elemental analysis, FT-IR spectrophotometer and 1H NMR spectroscopy. The designed molecular structure of ILs, with N atoms, makes it good corrosion inhibitor via the adsorption of ILs on the carbon steel surface to suppress both anodic and cathodic processes. The inhibition efficiency increases with increased ILs concentration.
