Imidazolinium inhibitor for mild steel in aggressive conditions
conference contribution
posted on 2015-01-01, 00:00 authored by Anthony SomersAnthony Somers, A L Chong, D R MacFarlane, Maria ForsythMaria ForsythAn organic salt comprising of an imidazolinium cation and a 4-hydroxy cinnamate anion has been shown to be a viable inhibitor for reducing the corrosion of steel in 0.01M NaCl aqueous solutions under acidic, neutral and basic conditions. The efficiency is particularly high at pH 8 (86%). Of most significance is that the individual components of this compound do not inhibit as effectively at equivalent concentrations, particularly at a pH of 2, suggesting there is a true synergy resulting from the combination of anion and cation. The immersion studies show the efficacy of these inhibitors to stifle corrosion as observed from optical, SEM and profilometry experiments. The mechanism of inhibition appears to be dominated by anodic behavior and further surface characterization work will investigate the origin of this inhibition and the synergy observed.
