“…In previous works, ethoxylated surfactants were used as corrosion inhibitors to prevent the dissolution of carbon steel in acidic solutions. The inhibition efficiency increased with an increase of ethylene oxide or propylene oxide units [6][7][8][9][10][11][12]. In the present study, we prepared and investigated four nonionic surfactants based on vanillin as carbon steel corrosion inhibitor in water-based drilling mud.…”

Four eco-friendly nonionic surfactants based on vanillin were investigated as corrosion inhibitors against carbon steel dissolution during the drilling process in the oil field. The corrosion inhibition efficiencies of the tested compounds were determined using weight loss, electrochemical polarization, and electrochemical impedance techniques. The data obtained show that the nonionic surfactants prevent the corrosion of drilling tools and their inhibition efficiency increased with an increase in their concentration. Tafel curves revealed that the surfactants under study act as mixed inhibitors. The adsorption of the inhibitors on carbon steel surface decreases the doublelayer capacitance. The inhibition efficiencies of the surfactants were influenced by their chemical structure and surface activity.

Three gemini cationic surfactants as biodegradable corrosion inhibitors for carbon steel in HCl solution

Three gemini cationic surfactants with different hydrophobic spacer chain lengths were synthesized and characterized. The inhibition effect of N,on the corrosion of carbon steel in 1.0 M HCl solution at 25-60°C was studied by weight loss, potentiodynamic polarization, and electrochemical impedance spectroscopy. The results show that the synthesized inhibitors are effective inhibitors even at very low concentration, and the adsorption on the carbon steel surface obeys the Langmuir adsorption isotherm. Potentiodynamic polarization curves reveal that the synthesized inhibitors behave as a mixed-type inhibitor. Adsorption of used inhibitors led to a reduction in the double layer capacitance and an increase in the charge transfer resistance. Thermodynamic parameters have been obtained by adsorption theory. Surface activity and corrosion inhibition relationship were discussed. The biodegradability of the synthesized surfactants showed their readily biodegradation in the open environment and were considered as environmentally friendly corrosion inhibitors.

“…In most cases, however, it is due to the adsorption of these compounds onto the surface of metals which can reduce the extent of corrosion through thermodynamics or kinetics phenomena [3][4][5][6]. The effectiveness of any corrosion inhibitor is dependent on the type of metal and properties of the corrosive environment [7][8][9][10][11]. Most of the well-known organic inhibitors are heterocyclic compounds containing p-electrons, heteroatoms like N, O, or S and aromatic rings [12][13][14][15].…”

The inhibition effect of new synthesized amphoteric and di‐cationic surfactants, namely: 4‐((((1‐dodecylpyridin‐1‐ium bromide)‐4‐yl)methylene)amino)benzoate sodium (I) and 1‐dodecyl‐4‐(((1‐dodecylpyridin‐1‐ium‐4‐yl)imino)methyl)pyridin‐1‐ium bromide (II), respectively, on the corrosion of carbon steel in 1 M HCl have been investigated using electrochemical impedance spectroscopy, Tafel polarization and weight loss measurements. The inhibition efficiencies obtained from all methods employed are in good agreement with each other. Tafel polarization studies showed that the surfactants are mixed type inhibitors. The adsorption of two compounds onto the surface of carbon steel in 1 M HCl obeys the Langmuir isotherm. Adsorption thermodynamic parameters reveal that the adsorption of inhibitors is a mixture of physical and chemical adsorption.
