Experimental and Theoretical Studies for Schiff base as best Corrosion inhibitor

Khalida F. Al.Azawi

Abstract


In present work, hypothetical and experimental investigations of the corrosion inhibition of mild steel in hydrochloric acid solution utilizing Schiff base namely 2-(4-(dimethylamino)benzylidene)hydrazinecarbothioamide (DH), was done. The inhibition characteristics of DH for the corrosion of mild steel in 1 M hydrochloric acid solution was explored utilizing weight loss strategy. The outcome has demonstrated that the DH is an excellent inhibitor of corrosion of mild steel in HCl. Inhibition efficiencies were 81%, 69% and 36% at 303K, 313K and 323K respectively, that mean the inhibition efficiency of the DH as corrosion inhibitor diminished as temperature expanded and expanded with expansion in concentration. The corrosion inhibition DH was synthesized and it structure was elucidate based on spectroscopic techniques.

Keywords
