Experimental and theoretical tools for corrosion inhibition study of mild steel in aqueous hydrochloric acid solution by new indanones derivatives

Mathematical Models Generated for the Prediction of Corrosion Inhibition Using Different Theoretical Chemistry Simulations

“…Corrosion protection as a result of a film formation process is mainly associated with sorption processes. The organic compounds adsorbed on a metal surface replace the pre-adsorbed water molecules and prevent the dissolution of the metallic surface, reducing the interaction between the metal surface and corrosive electrolytes [ 21 ].…”

“…Among the compounds proposed as corrosion inhibitors we find: N-containing heterocyclic organic molecules such as imidazole, benzimidazole, bis-benzimidazoles, amine, Schiff base compounds and alkaloids (e.g., papaverine, strychnine, quinine, and nicotine); S-containing compounds that comprise sulphonamides-which possess a large number of functional groups that are potential adsorption centres (-NH 2 group, -SO 2 -NH- group, O and/or N heteroatoms and aromatic rings)-, sulfonates, thiols, and thioaldehydes; O-containing compounds that can include benzoates, aldehydes, indanone derivatives; and finally, P-containing compounds as phosphonate derivatives and heteroatom-containing compounds such as azoles. The studies reveal that the inhibition of corrosion processes is mainly attributed to the formation of donor-acceptor complexes [ 11 , 12 , 18 , 19 , 21 , 24 ].…”

“…Indanone derivatives have been also investigated as corrosion inhibitors for mild steel in hydrochloric acid. Saady et al [ 21 ] used three indanone derivatives as corrosion inhibitors reaching corrosion inhibition efficiencies in the interval 87–92% (evaluated by weight loss). The selected indanone derivatives are considered environmentally benign, their effect as corrosion inhibitors can be attributed to the aromatic rings with conjugated double bonds that allow their easy adsorption on metallic surfaces, as well as to the presence of an electron-releasing methyl group that enhances the adsorption of the molecule on a metallic surface.…”

Experimental and theoretical insights on the adsorption and inhibition mechanism of (2E)-2-(acetylamino)-3-(4-nitrophenyl) prop-2-enoic acid and 4-nitrobenzaldehyde on mild steel corrosion

“…6,[10][11][12][13] The use of organic inhibitors is one of the most commonly used methods in this field, especially in the acidic medium. 2,5,6 These inhibitors adsorb firstly on the surface of metals and intervene in the reaction processes of corrosion to reduce the corrosion rate. 1,2 The benzaldehyde derivatives are widely used as corrosion inhibitors, especially in acidic medium.…”

Performance of Synthesized Acetone Based Inhibitor on Low Carbon Steel Corrosion in 1 M HCl Solution

“…Therefore, for current study the values of adsorption heat have been considered within the range of chemical adsorption. Saady et al [30] studied the performance of 2-(hydroxymethylene)-3,3-dimethyl-3-oxo-2,3-dihydro-1H-indene-1-one (HIO), 2-(4-methylbenzylidene)-3-oxo-2,3-dihydro-1H-indene-1-carboxylic acid (MIC), and 2-benzylidene-3-oxo-2,3-dihydro-1H-indene-1-carboxylic acid (BIC) on low carbon steel in hydrochloric acid. Three adsorption isotherms were investigated.…”
