Organotin Dithiohydrazodicarbonamides as Corrosion Inhibitors for Mild Steel-Dimethyl Sulphoxide Containing HCl
A few 1-aryl-2,5-dithiohydrazodicarbonamides and their triphenyltin and dibutyltin complexes have been studied as corrosion inhibitors for mild steel in dimethyl sulphoxide containing HCl at 25 ºC using electrochemical polarisation technique. Among dithiohydrazodicarbonamides, ethoxyphenyl derivative exhibited maximum inhibition efficiency (IE) followed by benzyl and phenyl analogues. The same order of IE was observed in their corresponding organotin complexes; however, IE of a complex was found to be significantly higher than that of the constituents ligand. All organotin complexes behaved predominantly as cathodic inhibitors. Triphenyltin complexes proved to be better corrosion inhibitors than their dibutyltin analogues.
