Abstract

The inhibition ability of Schiff base, 4-[(3,4-Dimethoxybenzylidene)amino]- 1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one on the corrosion of mild steel in 2M H2SO4 and HCl was studied by weight loss method.The inhibition efficiency of the Schiff base on mild steel metal was investigated at four temperatures and concentrations. The highest concentration 2x10-2M of the Schiff base gave inhibition efficiencies of 91%, 89%, 88%,and 60% at temperatures; 30°C, 40°C, 60°C,and 80°C respectively in H2SO4 medium, the same concentrations under the same conditions gave inhibition efficiencies of 94%, 95%, 97%,and 98% at temperatures; 30°C, 40°C, 60°C, and 80°C respectively in HCl medium, suggesting that the inhibitor performs better in HCl medium than in H2SO4 medium at high temperatures.
