Correlation between electronic structure and corrosion inhibition of copper in 3m nitric acid solution by some acetophenone aroyl hydrazone derivatives

Some acetophenone aroyl hydrazone derivatives have been studied by the inhibition of copper corrosion in 3M nitric acid solution. The structure of some acetophenone aroyl hydrazone derivatives were calculated 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 4.0 software to carry out linear regression. Based on regression results, we draw a conclusion on the relation between electronic structure and corrosion inhibitor efficiency of some acetophenone aroyl hydrazone derivatives
