THIRUMALAIKUMAR, M. e JEGANNATHAN, S.. Inhibition Effects of Nitrones on the Corrosion of Mild Steel in Organic Acid Media. Port. Electrochim. Acta [online]. 2011, vol.29, n.1, pp. 1-8. ISSN 0872-1904.
Aromatic nitrones have been synthesized and investigated for their function as inhibitor for the corrosion of mild steel in the organic acid media - 20% formic acid and 20% acetic acid at various inhibitor concentrations in the range of 50 - 150 ppm. Weight loss measurements and potentio-dynamic polarization studies reveal that the nitrones behave as mixed type inhibitors. Among the nitrones tested, para-methyl substituted derivatives perform better as inhibitors than the un-substituted nitrones.
