CORROSION INHIBITORY EFFECTS OF SOME SCHIFF'S BASES ON MILD STEEL IN ACID MEDIA

Weight loss and thermometric methods have been used to study the corrosion inhibition of mild steel in acidic solution (HCl and H2S0(4)) by Schiff s bases viz. N-(4-N,N-dimethylaminobenzal)-p-anisidine (SBj), N-(4-N,N-dimethylaminobenzal)-p-toluidine (SB2) and N-(4-N,N-dimethylaminobenzal)-2,4-dinit...
