Novel triphenyl imidazole based on 8-hydroxyquinoline as corrosion inhibitor for mild steel in molar hydrochloric acid: experimental and theoretical investigations

Helmet-Roled Molecules Carrying Double Metronidazole Frameworks and Phenyl Ring for Strengthening Adsorption and Anticorrosion on Mild Steel

“…The isothermal adsorption models of Langmuir (13), Temkin (14) and Freundlich (15) were used to fit the adsorption of the HMs on the surface of mild steel. 72 The fitting results are shown in Figure 15, Figure S3, and Figure S4, respectively.…”

“…At the current, organic inhibitor technology receives considerable interests to safeguard mild steel in acid environment due to the available and convenient performance. − The organic compounds that contain conjugated π-systems and heteroatoms such as N, O, P, and S are considered as the basic criteria to be used as the effective corrosion inhibitors. − These organic molecules are attached to a mild steel surface by adsorption, which may be processed by physisorption (such as electrostatic interaction, van der Waals force and π-empty orbitals interactions, and so on) and chemisorption (forming chemical bonds). , As a result, the adsorption of the organic inhibitors is followed by the supply of a protection barrier on mild steel that reduces the occurrence of corrosion of metals.…”

Experimental and Theoretical Assessments on Anticorrosion Performance of 2-(1H-benzimidazol-2-yl)-3-(4-hydroxyphenyl) Acrylonitrile for Copper in 1M HNO3

“…According to previous studies if ∆𝐺 0 𝑎𝑑𝑠 values exceeds -20 kJ/mol physical adsorption exists while less than -40 kJ/mol concern chemical adsorption. Both adsorption modes exist in the range of -20 kJ/mol to -40 kJ/mol [39,40]). The increase in 𝐾 𝑎𝑑𝑠 values with temperature reveals that increasing temperature enhance BHPA inhibition performance [41].…”

Synergistic effect of new imidazoline derivative and 2‐aminopyridine as corrosion inhibitors for Q235: Experimental and theoretical study

“…11,12 Imidazoline compounds have excellent corrosion inhibition properties, especially the quaternary ammonium salts of imidazoline formed by quaternization. [13][14][15][16] Due to their stable structure, low toxicity, non-irritating properties, good wettability, and bactericidal properties, they have become one of the research hotspots. 17,18 Imidazoline quaternary ammonium salt has excellent corrosion inhibition performance, Wang et al 19 synthesized imidazoline quaternary ammonium salt derivatives (PPLC) with excellent corrosion inhibition performance.…”

“…Due to the ability of lone electrons on heteroatoms to combine with the empty orbitals of metals, forming stable coordination bonds, and further enhancing the adsorption of corrosion inhibitors on metal surfaces through electrostatic attraction 11,12 . Imidazoline compounds have excellent corrosion inhibition properties, especially the quaternary ammonium salts of imidazoline formed by quaternization 13–16 . Due to their stable structure, low toxicity, non‐irritating properties, good wettability, and bactericidal properties, they have become one of the research hotspots 17,18 …”
