Novel Synthesis of Vegetable Oil Derived Corrosion Inhibitors

Abstract EN

Two different naturally occurring vegetable oils, Cress seed oil, and Linseed oil were chemically modified via novel one pot synthesis to produce fatty acid derived amides.

These were characterized by their ability to prevent corrosion of carbon steel in vigorously stirred, aerated seawater, one of the most corrosive naturally occurring environments.

Corrosion inhibitor efficiencies of up to 99.6% or a corrosion rate reduction factor of 250 in this medium is reported.

The one pot synthetic strategy means that the corrosion inhibitors can be made at very low cost.
