Study of relationship between electronic structure and corrosion inhibitor efficency of some 2-hydroxy-4-methylacetophenone benzoyl hydrazone compounds

Abstract

Some 2-hydroxy-4-methylacetophenone benzoyl hydrazone compounds have been studied by the inhibition of copper corrosion in 3M nitric acid solution. The structure of some 2-hydroxy-4methylacetophenone benzoyl hydrazone compounds were caculated by using the AM1 method of the quantum chemical program HyperChem 7.0. Results of the above calculation are coordinated with inhibitor efficiency (P) that is determined by experiment and both are applied to Statgraphics 4.1 software to carry out linear regression.
