ELECTROCHEMICAL AND CORROSION BEHAVIOR OF IRON IN PRESENCE OF SUBSTITUTED BENZOTRIAZOLES

The effect of benzotriazole (BTA), 5-methyl, 5-carboxy, 5-amino, 5-chloro, and a mixture of 5-carboxy and 4-carboxy benzotriazoles on iron corrosion and hydrogen evolution in H2S04 was examined. The results indicate that the COOH-BTA, and the mixed COOH-BTA were the most effective inhibitors on the basis of the quantity of organic required for maximum inhibition. An apparent linear free energy relationship was obtained for the corrosion rate at the concentrations of maximum inhibition.
