Comparative Inhibition Effect of Synthesized Fatty Amides Mixture, Pyridine and Pyrrole on Carbon Steel in Saline Environment

摘要

The inhibition effect of synthesized fatty amides mixture, pyridine and pyrrole as corrosion inhibitors on carbon steels in saline water had been compared using Linear Polarization Resistance Method (LPRM). It is still unknown which of these organics performed best than another. The experimental results showed that the inhibition effect of the synthesized fatty amides mixture is found to be better than pyridine and pyrrole, indicating the presence of various chain lengths of fatty amides molecules. These molecules provide a better surface on carbon steels than pyrrole and pyridine.
