Addition of amines to molasses and lees as corrosion inhibitors in sustainable de-icing materials

The Impact of Corrosion Inhibitors in Desalination Systems

“…Organic inhibitors adhere to metal surfaces and create a barrier or protective coating that keeps the metal from direct contact with the aggressive media. , Typically, these inhibitors contain functional groups like amines, carboxylates, or phosphates that can unite with metal ions to create a complex. , The protective coating slows down electrochemical processes and slows down corrosion. The newly identified pyrazolone derivatives recently showed promise as excellent inhibitors by Deyab et al Adsorption that effectively slowed acid corrosion was made possible by the inhibitor’s contact with the steel surface using its nitrogen and oxygen atoms.…”

“…Some common methods that have been used to analyse the corrosion rate was electrochemical impedance spectroscopy [9], electrochemical polarization [10], and weight loss [11]. Mild steel Epoxidized soybean fatty acids/ρsubstituted aromatic amines UV irradiation [16] X-80 3-Methoxypropyl-amine Simulated saline water [17] Carbon steel Methionine Carbon capture [18] Carbon steel N,N′-di-β-Dglucopyranosylethylenediamine, N-benzyl-N,N-bis[(3,5-dimethyl-1H-pyrazol-1-yl) methyl]amine Molasses [19] Stainless steel Amine grafted poly-(acrylic maleic) 3.5 % NaCl Although there have been extensive studies on the inhibitory effect of molybdate-organic inhibitors and amines-based on carbon steel, especially in the X-52 steel pipe, research on the synergy between molybdate and ethoxylated fatty amine on carbon steel in 3.5% NaCl environment has not been carried out. This paper is aimed to investigate the electrochemical corrosion behaviour of carbon steel in a 3.5% NaCl solution with a mixture of SM and EFA as a corrosion inhibitor.…”
