Inhibition Performance of Sugar-based Cationic Gemini Surfactants

More Information
  • Received Date: June 14, 2014
  • A sugar-based cationic gemini surfactant (C14-GDQ) was synthesized with glucose and N,N-dimethyldodecylamine as raw materials.The inhibition effect of the C14-GDQ on the corrosion of Q235 steel in 1 mol /L HCl solution was studied by mass loss method.The results showed that C14-GDQ was a good inhibitor in 1 mol/L HCl.Its inhibition efficiency increased with increasing C14-GDQ concentration,and inhibition efficiency became constant approximately when its concentration was higher than 0.1 mmol/L.The experimental data were treated with adsorption theory,kinetics and thermodynamics equations.Both the thermodynamic and kinetic parameters were obtained.
