Bioorganic compounds as copper corrosion inhibitors in hydrocarbon media

Triazolyl-acylhydrazone derivatives as novel inhibitors for copper corrosion in chloride solutions

“…These include thiazoles (benzotriazole), imidazoles, imidazolines, quinolines, thiols, Schiff bases, amino acids, naturally derived extracts, and pharmaceutical drugs. It has been demonstrated that these inhibitors, typically containing nitrogen, oxygen and sulphur hetero-atoms as major adsorption centres, are effective to inhibit corrosion of copper alloys in chloride solutions [2,[7][8][9][10][11][12][13], although some of them are inadequate to be both eco-friendly and high-efficient.…”

Study of cystine schiff base esters as new environmentally benign multifunctional biolubricant additives

“…DL-Valine has been studied as ecofriendly detergent/ dispersant additives for vegetable-oil based lubricants by blotters spot and it is categorized as good [23]. Cysteine and histidine, in hydrocarbon media has been examined as corrosion inhibitor for copper by a standard corrosion test [24].…”

Static secondary ion mass spectrometry investigation of corrosion inhibitor Irgamet ® 39 on copper surfaces treated in power transformer insulating oil

“…IEC 60296), for the dual purpose of providing electrical insulation and cooling of the copper conductors [1,2]. Sulphidemediated corrosion of copper and its alloys is a known issue in many applications of metallic materials, still subject of interest of the corrosion scientific community in both aqueous [3][4][5][6] and non aqueous environment [7][8][9][10]. In fact, previous studies have shown how certain organic compounds containing sulphur (e.g.…”

“…Benzotriazole (BTA) and its derivatives are among the most effective copper corrosion inhibitors [10,[21][22][23][24]. The protective film formed by BTA derivatives on copper surfaces may function both as a physical barrier to ionic or reactive species, and to attenuate copper dissolution [25].…”
