| Abstract: | The inhibition of copper corrosion in 1.5% sodium chloride solution was studied at 25, 35 and 45°C using different concentrations of thiosemicarbazide, p-methoxyphenyl isothiocyanate, p-methylphenyl isothiocyanate and p-chlorophenyl isothiocyanate and their corresponding condensation products with thiosemicarbazide. The inhibition efficiency IE of these compounds was evaluated by weight loss and electrochemical polarisation techniques. Substitution at p-position in the phenyl group resulted in change in IE in the following order for both the aryl isothiocyanates and their corresponding condensation products with thiosemicarbazide-p-chlorophenyl-< phenyl- < p-methylphenyl- <p-methoxyphenyl. |
