Corrosion inhibition, adsorption and thermodynamic properties of 2-aminopyridine derivatives on the corrosion of carbon steel in sulfuric acid solution

Synthesis and characterization of novel dicarbohydrazide derivatives with electrochemical and theoretical approaches as potential corrosion inhibitors for N80 steel in a 3.5% NaCl solution

“…Carbon steel has been examined using different corrosive media, including: hydrazones, 21 anti-tuberculosis drugs, 22 Stachys byzantina extracts, 23 interfacial assembled mesoporous polydopamine nanoparticles, 24 Zn( ii )-metal–organic networks using lemon verbena leaf extract, 25 2-aminopyridine derivatives, 26 and benzodiazepine derivatives. 27 …”

“…Consequently, the examinations of organic compounds on corroded carbon steel in acidic corrosive media showed many indentations; thus, they are mostly insufficient. [18][19][20] Carbon steel has been examined using different corrosive media, including: hydrazones, 21 anti-tuberculosis drugs, 22 Stachys byzantina extracts, 23 interfacial assembled mesoporous polydopamine nanoparticles, 24 Zn(II)-metal-organic networks using lemon verbena leaf extract, 25 2-aminopyridine derivatives, 26 and benzodiazepine derivatives. 27 The environmental signicance of hydrazide derivatives is due to their biocompatibility.…”

Corrosion Inhibition, Adsorption and Thermodynamic Properties of Poly (Sodium 4-Styrenesulfonate) on Carbon Steel in Phosphoric Acid Medium

“…where indicate that the formation of the activated complex is an endothermic process [37]. The average value of the difference between activation energy and enthalpy change (Eact-ΔHact) is 2.59 kJ/mol for all PSS concentrations, which is the exact value of the product of the gas constant and the average temperature of the experiment (313 K).…”

“…At the lowest concentration of PSS (5.0×10steel is significant 0.84. [3,32]. At higher temperatures, the PSS was desorbed from the surface of the carbon steel.…”

“…It is highly susceptible to corrosion when exposed to oxygen under extreme service conditions such as chemical contamination and moisture. This phenomenon of degradation causes enormous safety and economic losses in the form of lost production, replacement of corroded parts, accidents and public risks, especially in industry [3]. Various efforts have been made in the past to reduce the unfavourable reactions, mainly by common industrial developments such as acid pickling, acid descaling and acid cleaning, and the use of corrosion inhibitors is one of the best methods.…”
