Coconut Diethanolamide as a New Corrosion Inhibitor for Cold-rolled Steel

Coconut Diethanolamide as a New Corrosion Inhibitor for Cold-rolled Steel Li, Xianghong, Shuduan Deng, and Guanben Du. Journal of the Taiwan Institute of Chemical Engineers 131 (2022): 104171.

Non-ionic surfactants have the advantages of simple preparation, low toxicity, and high surface activity, making them potential corrosion inhibitors with good application prospects. Coconut diethanolamide (CDEA), as a non-ionic surfactant, does not have a cloud point compared to other non-ionic surfactants, and its hydrophilic head with O=C-N amide groups gives CDEA good hydrolytic stability.

CDEA is an efficient corrosion inhibitor, with a maximum inhibition efficiency of over 95% for 50mg·L^-1 CDEA in 1.0M HCl and 92% in 0.5M H₂SO₄ as measured by weight loss method. The adsorption of CDEA on CRS surface follows the Langmuir isotherm, with a standard adsorption Gibbs free energy of approximately -40 kJ·mol^-1. CDEA can act as a mixed inhibitor in both acids, but exhibits stronger anodic inhibition in HCl solution. The presence of CDEA significantly increases charge transfer resistance and decreases double layer capacitance. The inhibition efficiency order is 1.0M HCl > 0.5M H₂SO₄. A series of micro-morphologies observed by SEM, AFM, and CLSM confirm the effective inhibition of steel by CDEA in strong acids.
