Corrosion inhibition of mild steel in acid medium by new benzonitriles

“

Corrosion inhibitors: Many organic compounds have been studied, but too many of the compounds are not subjected for rational design. We contemplate inhibitory action with molecular structure along with cost efficiency of the synthesis. This paper in series of publications involving the use of compounds synthesized which otherwise is discarded as waste. For other papers, please refer; H. Lgaz, K. S. Bhat, R. Salghi, Shubhalaxmi, S.
