Abstract

ABSTRACT The compound 6-methylquinoxalin-2 (1 H)-one (Q-CH3) was synthesized, and its inhibiting action on the corrosion of mild steel in 1M HCl was investigated by various corrosion-monitoring techniques: electrochemical and weight-loss measurements. Results showed that this compound has fairly good inhibiting properties for steel corrosion in acidic medium, with efficiencies of around 97% at a concentration of 10− 2 M. The protection ...
