Abstract
The effect of the chemical structure of 2-mercaptobenzimidazole (MBI-2 ) derivatives on their inhibitive properties was quantitatively estima ted. An n-Cl substituent in the benzene ring imparted 2-MBI with the h ighest inhibiting efficiency in the media investigated (HCl, HC1+ H2S, and H2SO4, pH 1). This correlated with the positive bridge effect and most active chemisorption of the inhibitor due to the four reaction c enters involved: sulfur, nitrogen, and oxygen atoms and the benzene ri ng.
