Characterisation of a new tripyrazole derivative as inhibitor for the steel corosion in acid solution

The inhibition of corrosion of steel in 1 M HCl solution by newly synthesised pyrazole derivatives has been studied by weight loss and polarisation techniques at 308?K. Its inhibitory power is compared to N,N -bis(3,5-dimethylpyrazol-1-yl-methyl)-pentanolamine (Bipyr). The results obtained reveal th...

Description
Summary:The inhibition of corrosion of steel in 1 M HCl solution by newly synthesised pyrazole derivatives has been studied by weight loss and polarisation techniques at 308?K. Its inhibitory power is compared to N,N -bis(3,5-dimethylpyrazol-1-yl-methyl)-pentanolamine (Bipyr). The results obtained reveal that tripyrazole exhibits a good protection. Inhibition is found to increase with increase in inhibitor concentration. The inhibition behaviour of the compound has been explained on the basis of molecule size and charge density of adsorption active centres. The adsorption phenomenon obeys the Langmuir adsorption isotherm model.
