Corrosion inhibition of a new Schiff base derivative with two pyridine rings on Q235 mild steel in 1.0 M HCl

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.…”

Yumuşak Çeliğin Korozyon Davranışı

“…Literatürde piridin ve türevi bileşikler korozyona karşı inhibitör olarak sıkça kullanılmaktadır [1][2][3][4][5][6][7][8]. Bu bileşiklerin en büyük avantajı ise yapılarındaki konjuge çift bağlar ve düzlemsel yapıdaki hetero siklik halkada bulunan N atomudur.…”

“…Bu durumda aynı derişim değerlerinde, diğerlerine kıyasla [1][2][3][4][5][6][7][8] daha az madde tüketimi sağlanabilir. Ayrıca 3AMP yapısında bulunan amin grubu sayesinde yumuşak çelik yüzeyine daha kuvvetli adsorplanabilir.…”

A combined electrochemical and theoretical study of pyridine-based Schiff bases as novel corrosion inhibitors for mild steel in hydrochloric acid medium

“…These compounds exhibited a maximum IE of 85-95% at 200 mgL −1 . Yan Ji et al, 22 reported corrosion inhibition action of Schiff base derived from pyridin-2ylmethyl-N,N-diethylaniline (BPMA) that showed corrosion inhibition efficiency 88.1% at 450 ppm. Hegazy et al, 23 derived Schiff bases from benzylidene thiourea that gave 80-90% inhibition efficiency at very high concentration range (150 mgL −1 ).…”
