Experimental Modeling of Inhibition's Mechanism of Cupronickel Alloy by DETA and EDA into Acid Corrosive Media

Corrosion Behavior of Carbon Steel in Diethylenetriamine Solution for Post-combustion CO2 Capture

“…In comparison, diethylenetriamine (DETA) boasts a higher CO 2 absorption capacity and a faster absorption rate due to its three amino groups, essential components in biophysical solvents for CO 2 capture. , Recognized as potential candidates for energy-efficient CO 2 capture, biphasic solvents, particularly liquid–liquid biphasic absorbents, have been extensively investigated . DETA’s relatively high molecular weight and elevated electron density on the nitrogen functional group enable it to act as an electron donor, forming ligand covalent bonds with metal surface electrons, thus rendering it suitable as an organic corrosion inhibitor in weakly alkaline and acidic corrosive media, such as seawater and CO 2 -saturated NaCl solutions. − Consequently, DETA is anticipated to exhibit a high absorption capacity without inducing significant corrosion, promising excellent application prospects.…”
