Abstract
A study of the mechanism of corrosion inhibition of mild steel by imidazolines and their precursors in a CO2 containing environment is carried out using Rotating Cylinder Electrode (RCE) and Linear Polarization Resistance (LPR) technique. Corrosion rate-time/concentration profiles (LPR) and minimum effective concentrations (MEC) obtained for a series of imidazolines and amides are discussed in terms of the respective contributions of their constituent parts (imidazoline ring, amide/amine group, hydrocarbon chain) to the overall corrosion inhibition. The formation of the inhibitor film is described in terms of bilayer/multilayer film model.
