Organotin dithiobiurets as corrosion inhibitors for mild steel-dimethyl sulfoxide containing HCl
Corrosion inhibition studies of mild steel in dimethyl sulfoxide containing HCl have been performed at 25°C using dithiobiurets and their triphenyltin- and dibutyltin complexes as inhibitors. The inhibition efficiency (IE) of these compounds was evaluated by electrochemical polarization technique. Among the ligands, best performance was exhibited by ethoxyphenyl derivative. The IE values of the ligands enhanced...
