Electrochemical effect of cationic gemini surfactant and halide salts on corrosion inhibition of low carbon steel in acid medium

Synergistic corrosion inhibition effect of quinoline quaternary ammonium salt and Gemini surfactant in H2S and CO2 saturated brine solution

“…After 12-3OH-12 is added at lower concentrations in the solution, 12-3OH-12 molecules can be cooperatively adsorbed on the spare active sites of steel surface, probably in perpendicular direction [32,58], to make the adsorption film more compact. As a result, the corrosion reaction is further retarded.…”

“…Since quinoline derivatives have outstanding inhibitive property in HCl and 3.5% NaCl solution [25][26][27][28] and Gemini surfactants are effective inhibitors in HCl, CO 2 -containing, and H 2 S and CO 2 coexistent solution [29][30][31][32][33], this research was designed to investigate the synergistic effect between quinoline quaternary ammonium salt (1-benzyl-quinolinium chloride, QB for short) and Gemini surfactant (1,3-bis(dodecyldimethylammonium chloride)-2-propanol, 12-3OH-12 for short) in a H 2 S and CO 2 saturated brine solution via electrochemical measurements. X-ray photoelectron spectroscopy analysis (XPS) was also used to determine the adsorption behavior of inhibitors on steel surface.…”

Synthesis, characterization and comparative evaluation of phenoxy ring containing long chain gemini imidazolium and pyridinium amphiphiles

“…In recent years the use of cationic amphiphilic aggregates in high technology areas such as soft templates for the synthesis of mesoporous materials [1][2][3][4][5], corrosion inhibitors [6][7][8][9][10], gene delivery [11][12][13] and antimicrobial activity [14,15] has considerably increased. These cationic amphiphiles are able to absorb at interface and form aggregation in both aqueous and non-aqueous solutions and thus are responsible for modification of physicochemical properties of the system.…”

Synthesis and surface properties of a series of surfactants based on O-alkyl and O-perfluoro-N,N′-diisopropylisoureas

“…Hydrochloride and hydrobromide cationic surfactants in water exhibit interesting surface properties [1] that showed various applications as anti-corrosion additives [2][3][4]. Indeed, corrosion inhibitors, especially those based on hydrochloride cationic surfactants, are the most interesting because of the small size of the chlorine atom, improving their adhesion to metal [5].…”
