Synthesis of polymeric surfactant containing bis-cationic motifs as a highly efficient acid corrosion inhibitor for C1018 carbon steel

Abstract

The present study describes the synthesis and characterization of a Poly(methyldiallylammonium chloride)-based surfactant containing bis-cationic motifs 9 by a series of reactions. The synthesized polymer 9 was characterized by FTIR...

Synergistic effect of KI on the corrosion inhibition of a poly(diallylammonium chloride)-based cyclocopolymer containing bis-cationic motifs for mild steel corrosion in 20% formic acid

“…Overall, the negative sign associated with the value of ensures that the adsorption process is spontaneous. 19,40…”

“…2 Studies have shown that polymeric surfactants are very effective in arresting corrosion. [15][16][17][18][19] The hydrophilic portions of the surfactants interact with the metal surfaces, and the hydrophobic parts spread out toward the water molecules and repel them. This study explores the mild steel corrosion inhibition efficiency of a homopolymer (3), poly(diallylammonium chloride), and some copolymers (8a-c) containing pyrrolidine ring and a long hydrophobic/hydrophilic cationic pendant (5-20%) moieties (Scheme 1) in a 20% formic acid solution.…”

Experimental and theoretical investigation on the anti-corrosion characteristics of pyridine-substituted benzothiazole derivatives for mild steel in aqueous HCl

“…The presence of –NH 2 or –OH substituents invokes higher dipole moment for APYBT and HPYBT, which enhances the electrostatic interaction between those molecules and the metal surface. 79 From the optimized geometry of the inhibitor molecules and electronic disposition in the HOMO and LUMO levels, the mode of interaction between the inhibitor and metal is presumed. It is seen that all three BT-Py derivatives are almost planar (Fig.…”

N‐(4‐Chloromethylbenzyl)‐N, N‐dimethyldodecan‐1‐aminium Chloride: A Quaternary Ammonium Surfactant as Corrosion Inhibitor

“…However, a longer hydrocarbon chain has the reverse effect on how well it performs after a certain length. [23,24] Their decreased solubility explains this.…”

“…This is undoubtedly accurate for surfactant molecules with the ideal size. However, a longer hydrocarbon chain has the reverse effect on how well it performs after a certain length [23,24] . Their decreased solubility explains this.…”
