Abstract

Relationship between structure and inhibition behaviour of (E)-4-(2,3- Dihydro-1,3-benzothiazol-2-ylidene)-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one (P1) for mild steel corrosion: Experimental and theoretical approach

Corrosion inhibition behaviour of (E)-4-(2,3-Dihydro-1,3-benzothiazol-2-ylidene)-3-methyl-1-phenyl-1H-pyrazol- 5(4H)-one (P1) on mild steel corrosion in 1 M HCl was investigated at various concentrations by gravimetric and electrochemical techniques. The polarization curves indicated that (E)-4-(2,3-Dihydro-1,3-benzothiazol-2-ylidene)- 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one (P1) as mixed inhibitor. The adsorption of (E)-4-(2,3-Dihydro-1,3- benzothiazol-2-ylidene)-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one (P1) on mild steel leading to inhibition was found to follow the Langmuir adsorption isotherm. The quantum chemical calculations were carried out to establish the mechanism of corrosion inhibition.
