Synthesis, characterization and study of methyl 3-(2-oxo-2H-1,4-benzoxazin-3-yl) propanoate as new corrosion inhibitor for carbon steel in 1M H2SO4 solution

The brown algae Cystoseira Baccata extract as a friendly corrosion inhibitor on carbon steel in acidic media

“…The E a values in the presence of the CBE are higher than those of the un-inhibited acidic solution. This increase in E a value may be interpreted as physisorption [53].Moreover, Belghiti et al [54] explained that the increase in E a value can be attributed to an appreciable decrease in the adsorption of the inhibitor on the CS-surface with an increase in temperature. This means that an increase of temperature favored desorption over adsorption.…”

Enhancing aluminum foil performance in aqueous and organic electrolytes: dual-secure passivation with phthalocyanine as a corrosion inhibitor

“…The molecules that donate or accept electrons during adsorption onto metal surfaces are all good corrosion inhibitors. [17][18][19][20][21][22][23][24][25][26] Because of heteroatoms (N, O, S, and P), double/ triple bonds, or aromatic rings, the organic component is responsible for adsorption onto metal surfaces. 27 Even though "green" organic substances like surfactants, drugs, amino acids, ionic liquids, or biopolymers are also considered to be corrosion inhibitors, there is a pronounced preference for heterocyclic organic molecules, mainly those having oxygen, sulfur, or nitrogen.…”
