Novel Green Soybean Oil Derivatives as Corrosion Inhibitors for Mild Steel at 0.5 N HCl

Novel four green corrosion inhibitors were prepared via amination of brominated soybean oil using different types of amines (urea, thiourea, p- toluidine, and 3-amino benzoic acid). The prepared compounds were elucidated using FT-IR and 1H-NMR; they were evaluated as corrosion inhibitors at different temperatures (308, 318, 328 and 338 K) using weight loss method and chemical analysis method. The corrosion tests proved that the prepared compounds exhibit excellent corrosion inhibition properties at acidic medium.
