Abstract A new type of urotropine quaternary ammonium salt as corrosion inhibitor was synthesized through nucleophilic reaction with urotropine and bromohexane as raw materials, while methanol as solvent. Then, the corrosion inhibition effect of quaternary ammonium salt for QT-800 steel in 15% (mass fraction) HCl solution was assessed by mass loss measurements, IR spectrometer and SEM. The mechanism of corrosion inhibition was studied by quantum chemical density functional theory. The results indicated that the quaternary ammonium salt has good corrosion inhibition performance, when urotropine quaternary ammonium salt of 0.5% (mass fraction) was added into 15%HCl solution at 90 ℃, the inhibition efficiency for QT-800 steel could reach up to 98.41%. The complexes of the urotropine quaternary ammonium salt with polyethylene glycol, potassium iodide and propynol were prepared respectively, and they all showed good performance in corrosion inhibition. Quantum chemical parameters indicates that the chemical activity of the urotropine quaternary ammonium salt is mainly distributed on the molecular ring, which has a smaller energy gap than the urotropine, and a larger adsorption energy on the iron surface. Therefore, the reactivity of urotropine quaternary ammonium salt is higher than that of urotropine. The results of IR spectrum and SEM analysis reveal that the urotropine quaternary ammonium salt molecules could adsorb on the surface of QT-800 steel during the corrosion test in HCl solution.
