Weight loss and thermometric methods have been used to study the corrosion inhibition of mild steel in acidic solution (HCl H 2 SO 4 ) by Schiff's bases viz.N-(4-N,N-dimethylaminobenzal)-p-anisidine (SB 1 ), N-(4-N,N-dimethylaminobenzal)-p-toluidine N-(4-N,N-dimethylaminobenzal)-2,4-dinitroaniline 3 ).The efficiencies compared with those parent amines from which derived.Results observed these two are good agreement found be dependent on concentrations inhibitors as well acids.Inhibition efficiency all increases increasing concentration inhibitors.Efficiency also is more case HCl rather than .Inhibition was maximum up 95.55% for solution.Inhibition synthesised much their amines.It that but decreases .
