Tóm tắt
INHIBITION OF MILD STEEL CORROSION IN HCl 2M SOLUTION BY 2-[4- HYDROXY-3 METHOXYBENZYLIDENE]-N-PHENYLHYDRAZINE CARBOTHIOAMIDE (HMBP) COMPOUND
This paper introduces results of synthesis of a new corrosion inhibitor named 2- [4-hydroxy-3-methoxybenzyliden]-n phenylhydrazincarbothioamide (HMBP). Its corrosion inhibition efficiency for mild steel CT3 in solution HCl 2M were determined by weight loss method, potentiodynamic polarization and electrochemical impedance spectroscopy. All three methods proved that the corrosion inhibitor is high effective to protect mild steel in 2M hydrochloride solution.
