South Korea - Corrosion Research - Synthesis and corrosion inhibition behavior of imidazoline derivatives based on vegetable oil

Bio-diesel-based 2-(2-alkyl-4,5-dihydro-1H-imidazol-1-yl)ethanol derivatives (A-DIEs) were prepared as green corrosion inhibitors to investigate their corrosion inhibition behavior.

Various A-DIE from vegetable oil (i.e. Soy-DIE, Palm-DIE, Castor-DIE) are studied for its corrosion inhibition properties as a function of concentration of A-DIEs.

It was found that even very small amounts of A-DIEs, e.g. 20 ppm, improved the corrosion inhibition property of mild steel in an acidic solution very strongly.
