(3E)-3-{[4-(phenylsulfonyl)]imino}-3,4-dihydroquino xalin-2(1H)-one (PSDQO) has been synthesized and it s inhibiting action on the corrosion of mild steel in 1 M H 2 SO 4 has been assessed by weight loss method at 303 K – 333 K. The results of the investigation show that t his compound has excellent inhibiting properties fo r mild steel corrosion in sulphuric acid. Inhibition efficiency increases with increase in the concentration of the inhibitor. The adsorption of the inhibitor was tested for Langmuir , Temkin, Flory-Huggin’s and El-Awady isotherm and proved physical adsorption. Quantum chemical calculations were employed to give further insight into the mech anism of inhibitive action of the inhibitor.
