ELECTRONIC STRUCTURE AND CORROSION INHIBITORS EFFIENCY OF SOME ACETOPHENONE BENZOYL HYDRAZONE DERIVATIVES

Abstract

    The corrosion of copper in 3M nitric acid solution was investigated when using someacetophenone benzoyl hydrazone derivatives as inhibitors. The structure parameters of thesecompounds are computed using AM1 method attached to HyperChem 7.0 software.The computed structure parameters are combined with practical inhibition efficiency (P) torun a multi-variables regression using Statgraphic 4.0 software. Based on regression results,we draw a conclusion on the relation between electronic structure and corrosion inhibitorsefficency of some acetophenone benzoyl hydrazone derivatives.
