Inhibiting effects of some oxadiazole derivatives on the corrosion of mild steel in perchloric acid solution was written by Lebrini, Mounim;Bentiss, Fouad;Vezin, Herve;Lagrenee, Michel. And the article was included in Applied Surface Science in 2005.Name: 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole This article mentions the following:
The efficiency of 3,5-bis(n-pyridyl)-1,3,4-oxadiazole (n-POX, n = 1, 2, 3), as corrosion inhibitors for mild steel in 1 M perchloric acid (HClO4) have been determined by weight loss measurements and electrochem. studies. The results show that these inhibitors revealed a good corrosion inhibition even at very low concentrations Comparison of results among those obtained by the studied oxadiazoles shows that 3-POX was the best inhibitor. Polarisation curves indicate that n-pyridyl substituted-1,3,4-oxadiazoles are mixed type inhibitors in 1 M HClO4. The adsorption of these inhibitors follows a Langmuir isotherm model. The electronic properties of n-POX, obtained using the AM1 semi-empirical quantum chem. approach, were correlated with their exptl. efficiencies using the linear resistance model (LR). In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7Name: 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole).
