Reflection infra-red studies of films formed by benzotriazole on Cu

The crystal and molecular structure of 2-mercaptobenzimidazole

“…Poling (1970) has shown this to be the case with benzotriazole and Cu in 0.1 M H2SO 4 where the protective layer was a polymeric complex of benzotriazole and Cu(1).…”

The crystal and molecular structure of 2-amino-4-phenylthiazole hydrobromide monohydrate

“…It is possible that corrosion inhibition in this case is caused by coordination of the organic molecule and the halide to cations on the metal surface. Poling (1970) has provided evidence for the formation of complexes on metal surfaces by demonstrating that the corrosion inhibition of copper, in dilute sulphuric acid solution, by benzotriazole (BTZ) occurs by the formation of polymeric [Cu(I)BTZ], layers several thousand ~ngstr6ms thick on the metal surface. The coordination of 2-aminothiazole to the M n ions of cobalt, nickel, and copper has been studied by Duff, Hughes &Rutt (1972) who report nitrogenbonded rather than sulphur-bonded complexes for this monodentate ligand.…”

1-hydroxy Benzotriazole as Corrosion Inhibitor for Mild Steel in 1 mol/L Hydrochloric Acid Solution

“…[7][8][9] Since 1947, benzotriazole (BTAH) had been considered as an efficient corrosion inhibitor for copper and its alloys. [10][11][12][13] For the low cast, its hydroxy derivative, 1-hydroxybenzotriazole (BTAOH) also has been discussed as corrosion inhibitor for copper, 8,[14][15][16] although it shows a lower inhibition efficient (IE) than BTAH. As a corrosion inhibitor for steel, Motales-Gil P. et al studied the corrosion inhibition of BTAOH for pipeline API 5L X52 steel immersed in 1 mol/L H 2 SO 4 aqueous solution.…”
