“…This process is considered to represent an interface inhibition according to Fischer’s classification. The surfactant inhibitor has many advantages, such as a high inhibition efficiency, low price, low toxicity, and easy production [14,15,16]. The problem of finding an inhibitor that has little or no impact on the environment has recently motivated numerous studies [17].…”

A new coumarin derivative, N,N′-((2E,2′E)-2,2′-(1,4-phenylenebis(methanylylidene))bis(hydrazinecarbonothioyl))bis(2-oxo-2H-chromene-3-carboxamide) PMBH, was synthesized and its chemical structure was elucidated and confirmed using spectroscopic techniques (Infrared spectroscopy IR, Proton nuclear magnetic resonance, 1H-NMR and carbon-13 nuclear magnetic resonance 13C-NMR). The corrosion inhibition effect of PMBH on mild steel in 1.0 M HCl was investigated using corrosion potential (ECORR), potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and electrochemical frequency modulation (EFM) measurements. The obtained results indicated that PMBH has promising inhibitive effects on the corrosion of mild steel in 1.0 M HCl across all of the conditions examined. Scanning electron microscopy (SEM) was used to investigate the morphology of the mild steel before and after immersion in 1.0 M HCl solution containing 0.5 mM of PMBH. Surface analysis revealed improvement of corrosion resistance in presence of PMBH.

“…In the protection of copper alloys in phosphoric acid solutions, 3-mercapto-1,2,4triazole, benzotriazole, thiophene, tetrahydrothiophene [143], 1-butyl-4-methylpyridinium tetrafluoroborate [144], oil of Artemisia Astéracées plant [145] and extract of sea algae Sargassum wightii [146] demonstrate weak inhibiting properties. Multicomponent mixtures (Table 2) containing urotropine, azomethine and an additive of hydrophobic origin are capable of preventing corrosion of titanium [113-115, 119, 120], indium [114][115][116][117]119] and tin [118] in 1 М H 3 PO 4 .…”

Better adsorption is observed for TPhCA on zinc with (-G ads ) = 28.9 kJ/mol [140] and for 1-butyl-4-methylpyridinium tetrafluoroborate on copper (23.3-24.7 kJ/mol) [144]. In all the cases, adsorption is described by the Langmuir isotherm.…”

The article summarizes the literature data and patents on the protection of steels and nonferrous metals in phosphoric acid solutions with various corrosion inhibitors. Some aspects of practical use of H 3 PO 4 solutions, their properties and corrosivity toward various metals are reviewed. It is shown that the overwhelming majority of individual organic and inorganic compounds, as well as composite inhibitors offered for the protection of metals in this medium are of low efficiency due to weak adsorption on metal surfaces. A promising method for the protection of steels in phosphoric acid media involves the use of formulations containing triazole derivatives and sulfur-containing additives. The components of these mixtures form polymolecular protective layers on the metal surface that are highly efficient in slowing down corrosion processes even at temperatures up to 100С. An important property of these protective layers is a strong chemical bond of the inhibitor molecules with the metal surface and with each other inside the layer. Inhibited H 3 PO 4 solutions resistant to the accumulation of corrosion stimulators-Fe(III) saltsmay become a new and promising field of use for this acid. The bibliographic list includes 170 sources.

In this paper, the possibility of using newly synthesized ionic liquid based on nicotinamide as a potential inhibitor of copper corrosion in an acidic sulfate medium was investigated. Inhibition efficiency of butyl-nicotinamide, [C4Nic]Br on copper corrosion in acidic (pH=3) 0.1 mol/dm3 sodium sulphate solution was analyzed using potentiostatic polarization measurements and electrochemical impedance spectroscopy (EIS). It was found that the investigated ionic liquid had inhibitory properties of the corrosion of copper in acidic media. The inhibitory effect of the test compound is manifested by rapid and spontaneous adsorption of [C4Nic]Br molecules on the copper surface following Langmuir’s adsorption isotherm. As a result, the cathodic corrosion current decreases, as well as the polarization resistance of the system, increases compared with the basic solution. The inhibition efficiency of the investigated compound largely depends on the applied concentration.
