Abstract: Mitigating the corrosion tendency of condensate water towards pipeline steel favors its direct reuse. A surpramole-cular assembly (CDCA) was prepared through saturated solution method based on β-cyclodextrin (β-CyD, host) and trans-cinnamaldehyde (CA, guest). The results of proton nuclear magnetic resonance spectra indicated that CA could assemble with β-CyD via the wide or narrow rim of hydrophobic cavity, in which the wide rim assembled was energy preferred. Phase solubility study showed that the ratio of host to guest was 1∶1 in CDCA owning an association constant of 786 mol-1. The total iron content of condensate water in the field test could be effectively inhibited after adding CDCA, which could be maintained ranging from 50 to 70 μg·L-1. Dyna-mic weight loss measurements indicated CDCA could efficiently alleviate the corrosion of mild steel in the condensate water, and thus retard the permeation of corrosion product into the bulk water; the inhibition efficiency could reach 94.1% in the presence of 150 mg·L-1 CDCA at 298 K. Potentiodynamic polarization curves showed that CDCA inhibited the cathodic and anodic processes simultaneously, which could categorized as an anodic-dominated mix type corrosion inhibitor. Both the results of electrochemical impedance spectroscopy and linear polarization measurements revealed the polarization resistance could be enhanced in the presence of CDCA. Surface analyses disclosed only guest molecules (CA) adsorbed on the steel surface, which was verified by molecular dynamics simulation. Quantum chemistry calculations supported that CA adsorbed parallelly on the steel surface.
