Experimental and theoretical evaluation of N, N-Bis(2-pyridylmethyl)aniline as a novel corrosion inhibitor for mild steel in hydrochloric acid

Inhibition of mild steel corrosion in hydrochloric acid using two novel pyridine Schiff base derivatives: a comparative study of experimental and theoretical results

“…[18][19][20][21][22] However, the most studied pyridine derivatives contain only one pyridine ring, and investigations involving compounds with two or more aromatic rings are rare. [23][24][25] As is well known, the inhibition potential is inuenced by many factors, such as electronic structure, steric hindrance effects and aromaticity. 26,27 Hence, it is difficult to predict the corrosion inhibition ability of a novel organic compound with a Schiff base group and more than one aromatic ring.…”

“…In recent decades, quantum chemical methods have proven to be useful computational approaches in investigating the molecular structure and elucidating the reactivity and electronic structure of inhibitors. [23][24][25] Reviews on density functional theory (DFT) as a powerful tool in the design of corrosion inhibitors have been published by I. B. Obot, C. D. Taylor and G. Gece.…”

Adsorption and Corrosion Inhibition Properties of Butanolic Extract of Elaeoselinum thapsioides and Its Synergistic Effect with Reutera lutea (Desf.) Maires (Apiaceae) on A283 carbon Steel in Hydrochloric Acid Solution

“…7. The equivalent circuit consist of a solution resistance (R s ), constant phase (CPE), and polarization resistance (R p ), which including charge transfer resistance (R ct ), diffuse layer resistance (R d ), the accumulated species at the metal/solution interface (R a ) and the resistance of inhibitor film at the steel surface (R f ) (R p = R ct + R d + R a + R f ) [46,47]. The constant phase element (CPE), is replaced by the capacitance of a pure electrochemical double layer and is given by the relation below: Fig.…”

Recent Natural Corrosion Inhibitors for Mild Steel: An Overview

“…Synthetic compounds containing multiple bonds and heteroatoms are effective inhibitors, but at the same time the processing time, cost, and their toxic nature have compelled researchers to look for alternatives [6]. The inhibiting effect of some of these synthetic organic compounds on the corrosion of mild steel has been recently reported by several authors [1,5,10,[12][13][14][15][16][17][18][19][20]. However, most of the compounds that constitute these inhibitors are expensive and toxic to human and the environment.…”
