Abstract :

Most organic compounds contain heterocyclic atoms such as nitrogen, sulfur, oxygen and multiple bonds in the molecules. Heterocyclic compoundshave paying attention a significant curiosity for their highlyelectron-donating and strong coordination abilities, andstill receive much consideration because of their applications. One of the vital applications of heterocyclic compounds is corrosion inhibition against metals. The inhibitor forms a film onto the metal surface by either physisorption or chemisorption. The adsorption process, inhibition mechanism, and inhibition efficiency depend on the electronic and structural properties of the inhibitor, the temperature and pressure of the reaction, the nature of the metallic surface, and the flow velocity of corrosive medium. In this review the corrosion inhibition properties of heterocyclic compounds towards the metal surface in different media are focused.
