Study of Corrosion Behavior of N′-(2-(2-oxomethylpyrrol-1-yl)ethyl)piperidine for Mild Steel in the Acid Environment

The corrosion inhibition of mild steel in 1 M hydrochloric acid solution by N'-(2-(2oxomethylpyrrol-1-yl)ethyl)piperidine (N-OPEP) was studied employing weight loss techniques. The experimental findings revealed that N-OPEP is the most excellent corrosion inhibitor, and the inhibitory performance increases with an increase in the inhibitor concentration. Furthermore, the inhibition efficiency decreases with an increase in the solution Temperature. The adsorption of inhibitor molecules on a mild steel surface followed Langmuir's isotherm model and was found to be spontaneous. Scanning electron microscopy (SEM) photographs approved the formation of a protective layer of the inhibitor molecules on the surface of mild steel.

Automated summary

The corrosion inhibition of mild steel in 1 M hydrochloric acid solution by N'- (2- (2oxomethylpyrrol-1-yl) ethyl) piperidine (N-OPEP) was studied, and it was found to be an excellent corrosion inhibitor with its inhibitory performance increasing with inhibitor concentration but decreasing with solution temperature. The adsorption of inhibitor molecules on the mild steel surface followed Langmuir's isotherm model and was proven to be spontaneous. Scanning electron microscopy (SEM) photographs confirmed the formation of a protective layer of the inhibitor molecules on the mild steel surface.
