Fatty Amides from Crude Rice Bran Oil as Green Corrosion Inhibitors

Due to its high oil content,this research proposes the use of an agroindustrial byproduct (rice bran) as a sustainable option for the synthesis of corrosion inhibitors. from the crude rice bran oil,the synthesis of fatty amide-type corrosion inhibitors was carried out. the corrosion inhibitory capacity of the fatty amides was evaluated on an api x-70 steel using electrochemical techniques such as real-time corrosion monitoring and potentiodynamic polarization curves. as a corrosive medium,a co2-saturated solution (3.5% nacl) was used at three temperatures (30,50,and 70°c) and different concentrations of inhibitor (0,5,10,25,50,and 100 ppm). the results demonstrate that the sustainable use of agroindustrial byproducts is a good alternative to the synthesis of environmentally friendly inhibitors with high corrosion inhibition efficiencies. © 2017 e. reyes-dorantes et al.
