Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine, is researched, Molecular C12H10N6, CAS is 1671-88-1, about Inhibitor effects of triazole derivatives on corrosion of mild steel in acidic media.COA of Formula: C12H10N6.
The inhibitive action of triazoles on the corrosion of mild steel was studied through weight loss and various electrochem. techniques. Results obtained show that these organic compounds are good inhibitors. Triazoles are able to reduce the corrosion of steel more effectively in 1M HCl than in 0.5 M H2SO4. Potentiodynamic polarization studies clearly reveal the type of inhibitor. Changes in impedance parameters (the charge transfer resistance Rl and the double layer capacitance Cdl) are related to adsorption of triazoles on the metal surface, leading to the formation of a protective film which grows with increasing exposure time. The adsorption of these inhibitors on the mild steel surface in both acids obeys the Langmuir adsorption isotherm. The comparative study of corrosion inhibition of triazole derivatives indicates that the efficiency of the 4-aminotriazole is greater than that of the 4H-triazole.
