Evaluation of N,N-Dimethylformamide as Corrosion Inhibitor on API 5L X70 using 3% NaCl
Published online by Cambridge University Press: 16 July 2019
Abstract
Dimethylformamide (DMF) has been tested as corrosion inhibitor in a metallic material like API 5LX70 in a corrosive solution of 3% of NaCl and using electrochemical technique as electrochemical impedance spectroscopy. The results showed that 20 ppm is the best concentration to protect the metallic surface of API 5L X70 with η∼ 94%. Hydrodynamic conditions (100 and 1000 rpm) demonstrated that the DMF at different concentration afforded moderate protection against corrosion with inhibition efficiency ∼70%. Finally, the adsorption of this compound follows the Langmuir isotherm with a chemisorption-physisorption process.
