Abstract
A novel N,N'-(azanediylbis(ethane-2,1-diyl))dinicotinamide was prepared by the reaction of methylnicotinate with
diethylenetriamine. The chemical structure of the prepared compound was confirmed by FTIR and 1HNMR. The
prepared compound was examined as corrosion inhibitor for carbon steel in hydrochloric acid solutions using weight
loss, potentiodynamic polarization and electrochemical Impedance Spectroscopy Techniques. Tafel polarization studies
showed that the surfactant is mixed type inhibitor. The adsorption of the prepared compound on to the surface of carbon
steel in 1 M HCl obeys the Langmuir isotherm. Also, activation thermodynamic parameters such as Ea, ∆H* and ∆S*
were calculated using Arrhenius and transition state equations and discussed
