Use of Modified Mustard Oil in Steel Corrosion Protection

Abstract

Inhibitors are one of the most effective means of controlling corrosion of metals [1][2][3]. For instance, salts of fatty acids have found application as inhibitors of steel corrosion in neutral media [3]. However, their low solubilities and the formation of insoluble soaps in hard water make them difficult to use. To eliminate this disadvantage and improve their service properties, vegetable oils are modified, e.g., by sulfation. Sulfated Abstract -The inhibitive properties of sulfated mustard oil in neutral and alkaline media (3% NaCl and 0.25 M CH 3 COONa) in the presence of alkyl-and arylbenzoimidazole derivatives were studied. Mixtures of diethylammonium salts of sulfated mustard oil with benzoimidazole derivatives were found to be promising combined inhibitors of metal corrosion.
